Share to: It depends on the amount of heat, the salinity of the water, the surface area of the container, and the altitude. For canning purposes, using a non-glass top range, 6-8 cups o ⦠f water can take 5 to 10 minutes (for steam canning), while 4 gallons takes about 30 minutes (for water bath canning).

what temp do i turn stove on for pressure canning
|
Pressure canning is the only way to fresh preserve at 240°F. (Boiling water canners heat to only 212°F which is the temperature of boiling water.) Because Clostridium botulinum spores do not grow in the presence of acid, high-acid foods can be safely processed in a boiling-water canner.
|
Place in your pressure canner. Meat MUST be pressure canned. A hot water bath will not seal the jars correctly because meat is not acidic. Make sure to follow the directions on your individual canner. (I have a Presto 23 qt Pressure Canner, I love it!) Cook for 90 minutes at 10 pounds of pressure.

what forms where hot springs are releasing gases or interacting with the groundwater?
|
The shape of the land. A geyser is considered a type of hot spring, which is a pool of hot water that has seeped through a vent or opening in Earth's surface. By definition, the temperature of the water is at least 15°F (8.3°C) warmer than the average temperature of the surrounding air. It can reach as high as 200°F (93°C).
|
Geothermal mineral springsâoften called hot springsâare a fabulous wellness attribute of Sonoma County. Hot mineral springs, which exist around the world, are produced when geothermally-heated and mineralized groundwater emerges from the earth to form pools of water ranging from warmish to scalding.

what temperature is scalding milk
|
Test the temperature of the milk with an instant-read thermometer once the milk has begun to steam and show small bubbles. Milk is considered to be scalded once it exceeds a temperature of 180 degrees F. Select a heat-proof measuring cup that is capable of holding at least twice as much milk as you wish to heat.
|
If you buy milk directly from the milkman, you should heat it at 100 degree Celsius for less than 8 to 10 minutes. In case of milk packets, the content is already pasteurised and there is no need to boil it at high temperature and heat it for less than for 6 to 8 minutes at 100 degree Celsius.

Lancing or draining the boil Donât open a boil on your own because it is a painful procedure and the pus is very contagious. Once opened, the boil will drain pus for 2 or 3 days and then heal. Since the pus is contagious, the boil must be covered by a large 4 x 4 inch gauze bandage and tape. Change this bandage and wash the area with an antiseptic soap 2 times a day.

below the thermocline, the temperature of ocean water
|
Ocean water, with an average salinity of 35 psu, freezes at -1.94 degrees Celsius (28.5 degrees Fahrenheit). That means at high latitudes sea ice can form. The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit).90 % of the total volume of ocean is found below the thermocline in the deep ocean. The deep ocean is not well mixed. The deep ocean is made up of horizontal layers of equal density.he average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit). 90 % of the total volume of ocean is found below the thermocline in the deep ocean.

I bought this cover and I am finding that only the first several inches on the top gets warm and everything under is cold. I read some of the reviewers here saying something about the pump being on and the whole pool being heated, but I didn't really...
|
Here is what I do: the cover goes on at bedtime (9-10pm). The next morning about 9 to 10am I run the pump all day while at work. You have to run the pump 10 to 12 hrs anyway, do it while the sun is hitting the solar cover. Buy a timer for the pump. I have hit 78degF by doing this. Obviously you need lots of sun for this to work well.

Depends on temperature of water and if if your doing it indoors or outdoors and whether you use a windscreen or not. Alcohol stoves for backpacking burn a little hotter and with windscreen can boil 2 cups of water in 4-8 minutes. These Sterno canisters on youtube test took close to double that amount of time, about 20 minutes outdoors. Better for simmering or warming trays. Keeps coffee warm with out it boiling the pot dry camping. Not bad for scrambling eggs. I use a Fancy Feest alcohol stove to get thing boiling and hot in about 6 minutes then move it to the sterno stove to keep it warm.

The water or espresso coming out from the portafilter is measured only at 140- 150F. IS this normal? I thought extraction occured best at 195-205F.
|
That's a good question, so I measured the water temp for my BES860XL with a fast food thermometer. There was a little variability of water temp flowing from the filter, between 175-186F. Sitting in a pre-heated cup after the draw, the temp reading was 170F. I did not use the portafilter because it will act as a cooling fin and dissipate heat. Note that my machine is a refurb unit.
|
306 will be enough for it. Bought 306 here before but exchanged mine to my friends eheim filter because of too much noise. If you can stand for rattling noise, I'd love to recommend you to purchase 306.

Technically, you can make distilled water without boiling (evaporation + condensation capture-- solar stills as a simple example), although for all practical purposes, you really want to boil. As the previous respondents noted, this unit doesn't have any kind of temperature control beyond an automatic thermal break that shuts the unit off when it detects the pre-set threshold. As long as there is any remaining water on the bottom, the temperature will stabilize at ~100 C (212 F) internally (unless you live at higher altitudes and/or your source water has a boiling point greater than 100 C due to significant contamination).

Well it's a 250 watt element. So for 24 hours that's 6 kilowatt hours(kWh). So look on your electric bill for your kWh pricing. Multiply your kWh price by 6 and you've got the answer. For instance if your electric costs $0.12/kWh then it would be $0.72 to run the unit for 24 hours. Hope this helps!

Once the hour is up on the keep warm feature, how much longer does the water stay hot? Just wonder how well insulated the carafe is. Thanks
|
I would add that the plastic ones might be insulated and stay hot a little longer, but do you really want to drink water boiled in plastic? If you want water to stay hot a long time, get a vacuum sealed thermos, make sure it's vacuum sealed. It will stay hot for hours. This is the best kettle I've found to date, I think you'll be satisfied with it.

Yes, the stainless part comes out so a to go cup would fit. However the red rim at the bottom remains in place so taking a full Togo cup out could be tricky if you are not careful. It does make good coffee although mine makes the whole cup like crema.

This electric tea kettle is amazing!! I have another tea kettle that just annoys me (bought at Walmart). The Oster heats up 3x as fast as the Walmart-bought tea kettle. I've accidentally over-filled the Oster multiple times with no issues. It takes 1-2 minutes to heat up, and has a "keep warm" button that will stay on for 5-10 minutes. I usually fill it up, then keep the jug on my desk to keep re-filling my tea throughout the day. I re-fill it around lunch time, and it stays warm the whole time! That's hours worth of constant tea, and not having to get up from my desk while working. This kettle is well worth the price, I'd even pay more.

Here are the directions: DIRECTIONS FOR USE Hot tubs and spas: Use every 3 months or when spa is drained and refilled per the Simple Spa Care Program: 1. Remove filter and clean separately using Filter Clean. 2. Before spa is drained, add 1 bottle of Jet Clean to warm spa water. 3. Turn ON pump and run jets for 15 minutes. (Ensure that filter is not in spa). 4. Turn pump and jets OFF and let sit for 1 hour. 5. Turn pump ON and run jets and blower for 15 minutes. 6. Drain spa, hosing off inside spa walls while draining. 7. Refill spa according to the Simple Spa Care Program. *May need to partially fill spa and drain to help reduce foaming. NOTE: Some residual foaming may occur. If so, use Defoamer to suppress the foam. Jetted Bath Tubs: 1. Pour 8 oz (1/2 bottle) in tub with warm water before draining. 2. Turn jets ON for 15 minutes 3. Drain and rinse tub with clean water.

Can this unit be charged in 80-90 degree direct outdoor sun, other brand solar chargers would just stop working.
|
80-90 is not too bad, though the dashboard scenario is probably NOT a good idea, since dash temperatures probably move closer to 100+ degrees. It's an unfortunate fact, leading to a sub-optimal partnership, that batteries don't do well with too much heat, and solar panels need the sun. Even Li-ion and li-po batteries (which utilize less electrolyte than, say, a lead-acid battery) are affected by heat. Heat will SHORTEN the life of a battery while temporarily boosting efficiency by reducing the internal resistance (less resistance = more current). If you charge in 80-90 degree heat, try to keep your Opteka OFF the ground, if possible, maximizing air flow around it. If you continue to expose your battery to high temperatures, you are guaranteed to reduce its life. Nitty Gritty details : http://batteryuniversity.com/learn/article/discharging_at_high_and_low_temperatures P.S. I charge mine on the window sill of my office, where it gets only afternoon sun (about 3 hours). It stays cool, but won't charge to over 3 bars.

The output temperature is dependent on three things. 1)Input temperature 2)Gas Knob (Burner Setting) 3)Temp Knob (Water Flow) The output temperature but can be lowered quite a bit. Unless your source water is already quite warm I would not expect any issues keeping it below the 85F output. However since the input temperature is what determines the min and max it ultimately depends on your cold water input temp.

How long can you leave it on? Minutes? Hours?
|
No more than 15-20 min. Actual facial massage session should not be longer than 7-10 min.
|
I can take a shower by pumping the recommended number, getting wet, soaping, rinsing and by pumping again.... I can rinse/relax with the rest of the water. Prolly 5-6mins of warm water. I have never ran out of warm water while I needed it.The stand is not unstable at all. When I have a solid base such as wood or concrete it holds up fine to pumping. If I am on soft ground, I take it off the base.

can u use this for hot soup or chili how long will it stay hot maybe boil some hot water and pour in container then add a hot dog? thank u
|
According to the product description on Amazon, in most case the bottle can keep hot liquids hot and cold liquids cold for more than 12 hours and the bottle will not retain order or taste. So, you can put hot soup and add a hot dog too.

Yes Brittany, the complete heater is submersible. I have a 36 gallon corner aquarium and it is completely submersed. The entire unit as well as approximately 3 inches of the wire are under water. I've had it for about two months and it's working great!!! Good luck with yours!! :)

That is exactly right Grace. Bear in mind that the water is added on top of the rear section so if the unit is stored on a counter top under your wall cabinets it may have to be pulled out while in use and then slid back when finished. It takes less than 1 minute to brew and I have had no issue with dripping. My little drainage tray is still bone dry. You could lay a small napkin or folded paper towel on top of the drain under your cup also and never have to worry about drips. I keep a liter of bottled water nearby so I can add water whenever I want a cup. I don't like leaving water in a large tank since I don't drink cup after cup.

What is maximum water temperature for pump?

No idea. We don't use this any more because the pump was just too weak. In order for the pump to work with the panel, it has to be directly facing the sun, so one often has to go outside and change the direction of the panel.

Doesn't work as intended. Sorry, but don't buy it.

For the first time since the brand CROCK POT was invented, I am disappointed with one of their products - this item.
It doesn't keep the gravy warm. AT ALL. I used a thermometer and the hottest I could get this to was 130 degrees.
When I emailed Rival, they said it is supposed to be at 160 degrees.
I wrote them back, saying it only works at 130 degrees, and they never
responded.
This is what I did to try to get it to work: I filled the boat with boiling hot water, let that sit awhile, dumped that out, then put boiling hot gravy in the boat. It cooled off in no time.
VERY disappointed - before I purchased this tiem, I LOVED the idea - I thought it was PERFECT. I bought THREE of them. Bad idea.
Sorry, I want to write good reviews only but I don't want anyone else to get ripped off like I did.

The Bosch WH17 Tronic 6000 C Electric Tankless Water Heater is an attractive choice for adding hot water on demand to a kitchen or bathroom. It's 2.4 GPM max flow rate is adequate for supplying water to a shower, depending on the temperature of the input water. My interest in the system was for supplying the short burst and lower flow rate needs of a kitchen.
There was a time when on demand or "tankless" water heaters were rarely seen in the United States, and were mostly found in Europe and Asia. Tank style water heaters have predominated in the US for decades until recently. But, over the past ten years the market for tankless on demand water heaters has grown steadily, and there are now dozens of models and brands to select from. The one thing to keep in mind if this is your first purchase of a on demand water heater is that the seasonal weather of your location is important. Old style tank water heaters fill a reservoir tank with water from the supply line at whatever temperature the water is and then heat it to a set temperature. In the summer the water from the supply side is probably slightly tepid and in the winter, depending on your location, it may be chilled to almost frigid. The ability of an on demand water heater to heat water is a function of the temperature of the input water and the amount of time that the water spends circulating through the heating elements of the system. The colder the input water the lower the effectiveness of the heating element on the water before it passes through to the house side of the system. The only way to increase the amount of time that the water spends in the heating system is to lower the flow rate. If you live in an area with moderate seasonal temperature swings then it should be no problem. But the harder your winters are the lower the efficiency, in other words the lower the output temperature of an on demand system will be.
The Bosch WH17 Tronic 6000 is more than up to supplying a kitchen or single bathroom. But it would be unrealistic to expect it to serve more than a one bedroom apartment and, really, it's probably best to use it for one service area only, either for a bathroom or for a kitchen. Although the plumbing involved is do-able for a DIY home owner the installation on the electrical side should probably be handled by a licensed professional. The system requires an 80 amp dedicated line to the service panel to two 40 amp breakers on a 150 amp 240v service. You should keep these installation and electrical service needs in mind when calculating the final cost of switching to this kind of system. For supplying a whole house a 9+ GPM flow rate gas fueled tankless heater is probably the only way to go. The Bosch WH17 Tronic 6000 in general impressed me as being of higher quality overall than a RHEEM unit I previously owned and that the Bosch replaced. For kitchen hot water service it has been very good.

All the water outlets in my condo can only supply hot water for at most 2 mins and then I am left with cold water. I changed my gas water heater 2 days ago, but the problem continues. I was desperate when I thought the problem was finally resolved but was left with cold water again during a shower. Do anybody happen to know what is going on here ? Thank you a lot.
|
Hoping someone can give me some thoughts on what might be going on here so I can be a bit more informed when I call a plumber. Situation is, we got our water heater replaced a few years back and ever since this has been an issue. It's more noticeable when it's cold outside it seems, but still seems to be a year round problem. Whenever we use hot water, we basically run out of it within minutes. In order to get an acceptable amount of hot water (enough to take a 10 minute shower), we literally have to prime the water first. By that I mean I have to turn on the hot water, let it run for a couple of minutes, then turn it off and wait 20 minutes. Then when we go to use the hot water again we'll get hot water for a respectable amount of time. Now I am fairly ignorant to all this, but it seems a 71 gallon hot water heater should be capable of holding enough water to not need to be primed like this. I should be able to take a 30 minute shower, let alone 10 without running out. My shower this morning was decently warm for maybe 2 minutes before it was just warm-ish. So if anyone can give me some ideas on what might be going on I would appreciate it. We've just put up with this for some years assuming perhaps it was some eco friendly thing. Like the system doesn't maintain much hot water in the tank so it's not always running and only heats water up when you start to use it? I hope that isn't the case though and even so, I should be able to get more hot water out of it. Any help? UPDATE Sorry everyone, I meant to tell you all that the water heater was gas. The pilot light is lit. I don't recall the specific model though I can look that up if people think it will help. I have actually turned up the thermostat on it above the default and when the water heater is putting out hot water, it can be very hot. Too hot. But again, that requires us to prime it before we get any decent amount of hot water out. UPDATE 2 Looked it up, I believe this is the model info if that helps anyone: State Select: High Output. Model number: GS675XRRS 300

How large would the steam explosion at Chernobyl have been? So the of the HBO series began to cover the that led to them sending three divers into the water below the reactor to drain the tanks. This occurred after the initial explosion that destroyed the reactor, and after the fire in the core had been put out. But at this point the decay heat and remaining fission reaction kept the core at more than 1200°C, causing it to melt through the concrete floors below the reactor. And below the reactor were water tanks which contained 7,000 cubic meters of water (according to the TV show. If anyone has a real figure, I'd love to hear). When the lava of the melted core hit it, it would cause an enormous . Finally, my question: About how large would this explosion have been? The character in the show says "2-4 megatons" (of TNT equivalent, I assume). I'm pretty sure this is absurd and impossible. But real estimates are hard to come by. Other sources vary wildly, some repeating the "megatons" idea, and others saying it would've "". This still seems crazy. tl;dr: I know a lot of it hinges on unknowns and the dynamics of the structures and materials involved, so I can simplify it to a constrained physics question: Assuming 7,000 cubic meters of water instantly flashes to steam, how much potential energy is momentarily stored in that volume of steam occupying the same volume as the water did? I don't know what to assume the temperature of the steam is. There were hundreds of tons of core material at temperatures near 1200°C, so worst case scenario you could assume all the steam becomes that temperature as the materials mix. Best case scenario, I guess we could assume normal atmospheric boiling point (100°C)?

Overestimation Problem I had asked this problem earlier but I was too vague in how I asked it so I'm making a new post to be more specific. Problem: Say we have a series circuit with an ammeter, a cell with internal resistance and known emf, and a 10 ohm resistor. It is noticed that the resistor gets warmer. How would this affect the calculated value of the internal resistance? Here is the official answer: Here is my thinking: Since the resistor increases in temperature, it increases in resistance. Let's look at the equation ℰ = IR + Ir, where "ℰ" is emf, "I" is current, "R" is external resistance, and "r" is the internal resistance of the cell. if R increases and current is constant, in order to maintain constant emf, r must decrease. Where's the flaw in my thinking?
|
When the external resistor increases in temperature, why is the calculated value for internal resistance higher? Say we had a circuit with a cell (with internal resistance)and an external resistor of $10 \Omega$ as shown: The $10\Omega$ resistor then increases in temperature, leading to an increase in resistance in this resistor. My thinking was that since $10 \Omega$ resistor now has a value higher than $10\Omega$, more voltage drops across this resistor. Since your emf is constant, less voltage must drop across the internal resistor. Less voltage drop means less resistance. Where is the flaw in my logic?

Where does the energy for osmosis come from? A thought experiment: A U-shaped tube with semi-permeable membrane at the base. The tube is completely thermally isolated from its surroundings. The liquid (solvent) is at some temperature $T$. When solute is added to one side of the tube the fluid level on that side rises until the increased pressure due to gravity ($\rho gh$) equals the osmotic pressure. If I understand correctly, osmotic pressure could be used to do work (i.e. lift a weight as the solvent level in one side of U-shaped tube increases). Where does this energy come from? I guess it must be from the internal energy of the fluid. At this point has the temperature of the fluid decreased?? If so, has it decreased by exactly the work done against gravity divided by the specific heat of the fluid? What does the quantitative treatment of this problem look like?

After I pour a cup of tea, I can't drink it for 10 minutes. Will it stay warmer if I add the milk at the start, at the end or does it not matter? So preface, I work in engineering so I'm familiar with the basic principals of most fields in physics, but specialise in Civil Engineering so my knowledge of thermal physics is poor and I haven't studied it since high school. I have this recurring problem at work where I boil a kettle and pour myself a cup of tea. During the brewing process, I sometimes get interupted by a collegue who wants me to solve a quick problem, taking no more than 10 minutes of my time. I like to drink my tea at my desk while browsing the web so my tea will sit untouched for this time. I take my tea with milk. So my question: If I have already brewed my tea and have 10 minutes or so where I know I will not be able to drink it, should I; 1. Add the milk immediately after brewing 2. Add the milk immediately before drinking To maximise the temperature of the drink at the time of drinking. To me this is a closed system and it shouldn't matter what temperature the tea is when the milk is added as the same amount of time will elapse overall and the start values for each liquid is the same. But also if I add the milk early, it has more time to 'warm up' from fridge temperature. But if I don't add the milk early, then the tea is at a higher start temperature and intuitively to me will drop in temperature at a faster rate. The tea can probably be assumed to be at around 95C at the start and the milk 4C from the fridge.
|
Would a Cup of Tea Be Hotter If you Add the Milk Before or After Boiling Water? This is a bit of dispute between work colleagues. An answer would be greatly appreciated. My argument is as follows: If you add X amount of milk at a temperature of M to a mug at room temperature R before adding X amount of water at temp W, the result would be a cooler cup of tea than if you'd added the hot water first. This would be due to the milk reducing the overall temperature of the mug in the time that has been in it resulting in the addition of boiling water having less of an effect and resulting in a slightly cooler cup of tea/coffee. Conversely, if you add the hot water first, due to the mug being heated, the effect of adding the cool milk will be less and therefore the end result will be a hotter cup of tea. My Colleagues arguement is simply that it would not make a difference but without any form of justification. If anyone can give real scientific light to this issue it would be greatly appreciated :)

Why is my starting gravity low? In the fall of 2011 I made the leap from extract/partial kits to all-grain kits. I'm enjoying AG, but my SG is continuously below the expected. I have brewed 5 AG kits and 4 have had a low SG. My assumption is my sugar extraction during mashing (or sparging) isn't optimal. I heat my mash water to 165 and mash the grains for 60 minutes. Mashing levels out at 152. For Lautering I heat the water to 175-180. After I drain the initial mash I add the lautering water and let that soak for 10 minutes. the temperature levels out around 170-172. Then I drain into the kettle and being the boil. I aim for a gentle boil just enough to break the surface tension. I boil for 60 minutes, chill, rack, take a reading and pitch yeast. Here are some of the numbers type expected actual kit st paul porter 1.052 1.039 http://www.northernbrewer.com/shop/st-paul-porter-all-grain-kit.html belgium strong 1.067 1.055 http://www.midwestsupplies.com/superior-strong-ale-all-grain-kit.html troegs hop back 1.063 1.049 http://www.byo.com/stories/recipeindex/article/recipes/90-american-amber-a-pale-ale/2196-troeegs-hopback-amber-ale-clone The fuorth was the Phat Tyre kit from Northern Brewer. Can't remember the SG though. It was low. They taste great, but the numbers weren't "right". What can I adjust so the numbers are more inline with the recipe? Update Thank you for all the feedback. There are a number of factors for me to review and adjust. Given my current setup I will follow @mdma advice and recirculate the wort once and extend lautering to 30 minutes. It will be a week or two before I can attempt this, so it will be awhile before I report back again. Update #2 I now have some awesome local contacts who are helping me out with technique and trouble shooting. Another (major) issue I could be experiencing is draining the wort way too fast. According to my friend. The drain should be low and slow after cycling a gallon or 2 of wort. sparging should take ~2 hours. for each gallon drained plato/brix should drop 3 points and go no lower than 3-5 points at the end. the second recommendation is to heat up 3-5 gallons of water to 180 and poor it in prior to/while sparging. my first attempt using this technique proved successful with the gravity being a lot closer to the anticipated OG. I had some temp issues with the batch, but I was so focused on sparging that I ignored the temp. My guess is I would have been right on if my temp didn't fall so low. Update #3 I had the chance to brew with my mentor this weekend and he pointed out 2 glaring problems with my mashing technique. Starting mash temp is too low. I was heating my water to 10-12 degrees above target temp. He recommends 17 degrees. between grain absorption & the tun itself most of the heat dissipates within the first few minutes. This does go against what I originally said. That I was hitting my temp marks. Looking back I was hasty with my readings. I should not dump my sparge water (or lauter?) into the tun while draining the wort. The idea is to compact the liquid into the bottom of the tun thus compacting the sugars. I am stirring up the mash when I dump all sparge water in. We kept our sparge water 1-2 inches above the grain bed and our final results we excellent. A 3rd recommendation he made was to lower the pH of the water. tap water is ~7 and the ideal mash pH is 5.2. He added a solvent, which I cannot remember the name of, which did this for us. I'll be picking up some of that this weekend. Thanks to all who helped me out with this problem.

Is slow cooking for 24+ hours safe? I've been cooking a 15 lb (7 Kg) pork shoulder for 24 hours, and the temperature has been around 140°F (60°C) for both meat and liquid. I didn't realize the temp was so low until just now when I stuck a thermometer in it. Its a new (to me) slow roaster that is quite large, and has temperature written on the dial. I had the dial set to 275°F (135°C), but obviously the actual temperature is much lower that. I've turned up the temperature and will get it to a cooking temp of 275°F, but will it be safe to keep cooking the meat this way? I think I should get the meat close to 190°F (90°C).

Is there any danger to letting food cook in a slow cooker for a very long time? I've recently started using a slow cooker and I was thinking about recipes that could be cooked for days. My main concern is if there are any side effects for leaving food cooking for days that would make this plan unfeasible (dangerous to try). Since it is at cooking temperature, there wouldn't be any reason to worry about bacteria growing on the food. Liquid would be lost over time, which could result in burning if left unchecked, but if I add more every morning/night as needed, that too wouldn't be a problem. All I can see is that most recipes wouldn't end up tasting as well, but undesirable isn't equal to dangerous. There just seems to be something absurd with the notion of leaving food cooking for 5 days or even 2 weeks without there being any dangers, but I'm having a hard time figuring out what they would be.

Is this tenderloin safe to use? I have a vacuum sealed 8 lb. beef tenderloin that was in my refrigerator. The door was not closed completely and the refrigerator warmed to 42 degrees just at the beginning of the danger zone. The refrigerator could have been at that temp for 6 to 8 hours.

How large would the steam explosion at Chernobyl have been? So the of the HBO series began to cover the that led to them sending three divers into the water below the reactor to drain the tanks. This occurred after the initial explosion that destroyed the reactor, and after the fire in the core had been put out. But at this point the decay heat and remaining fission reaction kept the core at more than 1200°C, causing it to melt through the concrete floors below the reactor. And below the reactor were water tanks which contained 7,000 cubic meters of water (according to the TV show. If anyone has a real figure, I'd love to hear). When the lava of the melted core hit it, it would cause an enormous . Finally, my question: About how large would this explosion have been? The character in the show says "2-4 megatons" (of TNT equivalent, I assume). I'm pretty sure this is absurd and impossible. But real estimates are hard to come by. Other sources vary wildly, some repeating the "megatons" idea, and others saying it would've "". This still seems crazy. tl;dr: I know a lot of it hinges on unknowns and the dynamics of the structures and materials involved, so I can simplify it to a constrained physics question: Assuming 7,000 cubic meters of water instantly flashes to steam, how much potential energy is momentarily stored in that volume of steam occupying the same volume as the water did? I don't know what to assume the temperature of the steam is. There were hundreds of tons of core material at temperatures near 1200°C, so worst case scenario you could assume all the steam becomes that temperature as the materials mix. Best case scenario, I guess we could assume normal atmospheric boiling point (100°C)?

Can I shut off the water to my house and safely leave the water heater on while I'm away on vacation for a week? I plan to shut off the main water supply to my 2 story house before leaving for a week on vacation. I have an AO Smith gas 'powervent' water heater in the garage that I would like to set to 70*F rather than turning it off. Since there are no issues with freezing pipes here in the SF Bay Area, I wasn't planning to drain the water lines within the house. Would the cold water feed on top of the water heater need to be turned off also?

Why is my starting gravity low? In the fall of 2011 I made the leap from extract/partial kits to all-grain kits. I'm enjoying AG, but my SG is continuously below the expected. I have brewed 5 AG kits and 4 have had a low SG. My assumption is my sugar extraction during mashing (or sparging) isn't optimal. I heat my mash water to 165 and mash the grains for 60 minutes. Mashing levels out at 152. For Lautering I heat the water to 175-180. After I drain the initial mash I add the lautering water and let that soak for 10 minutes. the temperature levels out around 170-172. Then I drain into the kettle and being the boil. I aim for a gentle boil just enough to break the surface tension. I boil for 60 minutes, chill, rack, take a reading and pitch yeast. Here are some of the numbers type expected actual kit st paul porter 1.052 1.039 http://www.northernbrewer.com/shop/st-paul-porter-all-grain-kit.html belgium strong 1.067 1.055 http://www.midwestsupplies.com/superior-strong-ale-all-grain-kit.html troegs hop back 1.063 1.049 http://www.byo.com/stories/recipeindex/article/recipes/90-american-amber-a-pale-ale/2196-troeegs-hopback-amber-ale-clone The fuorth was the Phat Tyre kit from Northern Brewer. Can't remember the SG though. It was low. They taste great, but the numbers weren't "right". What can I adjust so the numbers are more inline with the recipe? Update Thank you for all the feedback. There are a number of factors for me to review and adjust. Given my current setup I will follow @mdma advice and recirculate the wort once and extend lautering to 30 minutes. It will be a week or two before I can attempt this, so it will be awhile before I report back again. Update #2 I now have some awesome local contacts who are helping me out with technique and trouble shooting. Another (major) issue I could be experiencing is draining the wort way too fast. According to my friend. The drain should be low and slow after cycling a gallon or 2 of wort. sparging should take ~2 hours. for each gallon drained plato/brix should drop 3 points and go no lower than 3-5 points at the end. the second recommendation is to heat up 3-5 gallons of water to 180 and poor it in prior to/while sparging. my first attempt using this technique proved successful with the gravity being a lot closer to the anticipated OG. I had some temp issues with the batch, but I was so focused on sparging that I ignored the temp. My guess is I would have been right on if my temp didn't fall so low. Update #3 I had the chance to brew with my mentor this weekend and he pointed out 2 glaring problems with my mashing technique. Starting mash temp is too low. I was heating my water to 10-12 degrees above target temp. He recommends 17 degrees. between grain absorption & the tun itself most of the heat dissipates within the first few minutes. This does go against what I originally said. That I was hitting my temp marks. Looking back I was hasty with my readings. I should not dump my sparge water (or lauter?) into the tun while draining the wort. The idea is to compact the liquid into the bottom of the tun thus compacting the sugars. I am stirring up the mash when I dump all sparge water in. We kept our sparge water 1-2 inches above the grain bed and our final results we excellent. A 3rd recommendation he made was to lower the pH of the water. tap water is ~7 and the ideal mash pH is 5.2. He added a solvent, which I cannot remember the name of, which did this for us. I'll be picking up some of that this weekend. Thanks to all who helped me out with this problem.

what happens to the water molecules that creates bubbles when you heat it

when a liquid boils, it literally turns into a gas (steam). As the water at the top of the pot evaporates, the gas can go straight into the air. But when it evaporates (boils) at the bottom of the pot, it forms bubbles that have to float up to the top

how to make hot water heater circulate
|
When a homeowner turns on a faucet, the cooled water sitting in the pipes circulates to the faucet first, so the homeowner has to wait for hot water. A hot water circulation pump sends cool water in the pipes back to the water heater through a return line. A pump circulates this water through the water heater as needed to keep it hot. This continuous loop of water through the water heater ensures that hot water is always available.

1 Answer from this member: Unless you are very experienced on replacing water heater elements, Yes, I strongly recommend draining the tank first. Otherwise, it could cause a lot of damage. To drain the tank, be sure to turn the breaker and supply water valve off and open any hot water tap in the house.

Save. There is no hard-and-fast rule for regularly changing the water heater elements on a hot water tank. The accepted norm is that when the water heater is no longer heating, the element has burned out and needs to be replaced. However, as a whole, water heater elements can last for years and give solid performance.

temperature of boiled water
|
Boiling water. The boiling point of a substance is the temperature at which the vapor pressure of the liquid equals the pressure surrounding the liquid and the liquid changes into a vapor.imilarly, a liquid at saturation pressure and temperature will tend to flash into its vapor phase as system pressure is decreased. There are two conventions regarding the standard boiling point of water: The normal boiling point is 99.97 °C (211.9 °F) at a pressure of 1 atm (i.e., 101.325 kPa).
|
The normal boiling point of water is 100oC because this is the temperature at which the vapor pressure of water is 760 mmHg, or 1 atm. Under normal conditions, when the pressure of the atmosphere is approximately 760 mmHg, water boils at 100oC.

Natural gas in the US is measured in CCF (100 cubic feet), which is converted to a standardized heat content unit called the therm, equal to 100,000 British thermal units (BTU). A BTU is the energy required to raise one pound of water by one degree Fahrenheit. A US gallon of water weighs 8.3 pounds (3.8 kg). So, to raise 60-gallon worth of 40 °C (104 °F) water up to 50 °C (122 °F) would require 60 à 8.3 à (122 â 50) = 35856 BTU, or approximately 0.359 CCF (35856/100,000), at 88% efficiency.

how does coolant reservoir work
|
Coolant to the Radiator. The radiator cap is like the air release system of a pressure cooker. When the radiator is hot, pressure builds up inside it, which releases some of the coolant from the cap. This overflowing coolant passes into the reservoir where it is stored until the engine cools.
|
The radiator in your vehicle cools your engine and needs water and coolant (antifreeze) to function. Rather than open the cap on the radiator, just check to see whether the liquid reaches the âFullâ line on the side of the coolant reservoir shown here. Itâs part of the coolant recovery system.

The boiling point of water is 100 °C or 212 °F, but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is used as a method of making it potable by killing microbes that may be present.

how long should a hot water heater last
|
Here are some signs that you may be ready for a new hot water heater; AGE: On average, your gas hot water heater should last anywhere between 8 to 12 years, while an electric model will last a bit longer at 10 to 15 years.
|
A water heaterâs useful life varies, depending on the type of water heater, the quality of the unit, and how well itâs been maintained. A traditional tank-type water heater lasts an average of eight to 12 years.

do tankless water heaters last longer
|
How does a Tank Water Heater work? Tank water heaters are heated by natural gas, propane gas, or electricity. There is no difference in the lifespan whether it is natural gas, propane or an electric water heater. Tankless water heaters have a longer lifespan of 20+ years. Water heater tanks are made out of a metal that has a sprayed-on glass lining. Inside the tank there is an anode rod, which is called the sacrificial rod in many instances.

1 They never run out of hot water. 2 They last five to 10 years longer than tank heaters. 3 They're more efficient with no standby heat loss. They take up less space and can even be installed on walls or outdoors with an anti-freeze kit.

what should my water pressure be at home
|
The typical inlet water pressure to a home is about 40 to 45 psi. Normally, it should not exceed 60 psi. The pressure regulator is usually preset to 50 psi. However, it can be adjusted anywhere from 25 to 75 psi with a simple turn of a screw, as shown above. To check the pressure, connect a pressure gauge to the nearest exterior faucet.
|
What is normal water pressure for house Could someone please let me know what the normal water pressure should be for my house? We have city water. I have installed an open system radiant heat system that is heated by my hot water heater. In the system there is a pressure guage that is showing 100psi give or take a few pounds. There is an expansion tank in the system and this pressure reading is constant regardless of whether the system is hot or cold. Running hot water elsewhere in the house causes a drop in water pressure of 2-3 psi.

how long does average hot water heater last
|
Typically, water heaters should last between 10-15 years and as long as you perform regular maintenance on it, it should last a good amount of time. Some things that you can do to prolong your water heater is drain it annually to remove sediment that may corrode your tank, especially if your city uses hard water.
|
Purchasing a hot water heater is an investment that should last for many years. While standard units with tanks that hold and heat large amounts of water last approximately 13 years, tankless or on-demand heaters -- either gas or electrically heated -- can last up to 20 years.

boiler and central heating cover compare
|
Boiler and central heating cover is supposed to give you peace of mind that-if thereâs a problem with your home heating-it'll be resolved as quickly as possible without the need for you to do a lot of leg work phoning local plumbers and heating engineers.f you have home insurance, check your policy carefully. Some policies do include boiler breakdown and home heating insurance, although you might have to pay a greater excess and the level of cover provided might not be as high as with a specific boiler policy.
|
A system (or pressurised sealed system) boiler uses a central heating expansion vessel which is usually installed in an airing cupboard. There is no need for an expansion tank in the roof as the combination of boiler and cylinder allows you to run mains pressure hot water from more than one outlet at the same time.

what is the opposite of heat of vaporization
|
â¢The molar heat of vaporization of water is 40.7 kJ/ mol. Condensation is the exact opposite of vaporization. The amount of heat released when 1 mol of vapor condenses is called its molar heat of condensation (DHcond).
|
1 Latent heat of vaporization (Lv): Refers to the heat lost by the air when liquid water changes into vapor. 2 This is also commonly known as the latent heat of evaporation. 3 Lv= -2500 Joules per gram (J/g) of water or -600 calories per gram (cal/g) of water.
