Basically 1 BTU will move 1 pound of water 1 degree Fahrenheit. There are 8.35 lbs in 1 gallon. There are 8.35*5=41.75 lbs in 5 gallons. To take water from 75 to 212 therefore requires: (212-75)*41.75=5720 BTU.
How many BTU does it take to boil 1 gallon of water?
One BTU is the amount of heat energy required to raise one pound of water by 1ºF. Water weighs 8.33 pounds per gallon so we can calculate that one gallon of water requires 8.33 BTU to raise the temperature 1ºF.
How many BTU do I need to boil water?
You have all heard of the BTU of heat energy (British Thermal Unit), it takes one BTU to raise one pound of water one degree Fahrenheit. So if the water in the pan on the stove is put in at 32°F, it will then require 180 BTU’s to bring the water to boiling temperature, or 212°F.
How fast will 15 000 BTU boil water?
On a 15,000 BTU burner, with water starting at 50°F it would take 12-15 minutes for 6 quarts (1.5 gallons) of water to boil. And 20-25 minutes to bring 12 quarts (3 gallons) of waters to a boil.
How do you calculate the heat needed to boil water?
One liter of water is about 1 Kg or 1000g, giving Q = m x (delta T) x Specific heat of water = 1000g x 80C x 1 cal/g C= 80,000 cal or 80 Kcals. Technically, 80 kcals that is the amount of heat needed to get the liquid water to 100C and anything extra would go into vaporizing the water into steam.
How many BTU do I need for a shrimp boil?
For backyard use, he recommends a 50,000 BTU burner and a regulator, a safety device that goes between the tank and the burner that will stop the flow of propane if the line ruptures. The height of the burner is important, too. It should not have a high center of gravity in case anybody bumps into it.
Is 18000 Btu enough for cooking?
Middle: 2,000–10,000 BTUs. Mid-range BTUs are good for everyday cooking like sauteing and frying. High: 12,000–18,000 BTUs. These high BTU burners are meant for high heat cooking like searing and stir-frying.
How long does it take to boil off a gallon of water?
If you are boiling water on a usual stove in a tank that conducts heat well, then it will take you approximately one hour to see the one gallon of water (if the water was cold when you started to simmer it).
Is 12000 Btu burn enough?
For most users, one power burner (12,000 BTUs or higher) is more than adequate—especially when paired with two medium-strength burners and one low burner for simmering. If you do a lot of cooking that requires quick high heat, such as stir-frying or searing, you may want to push the power up.
Does salt boil water faster?
Adding salt to water is going to do two things to water’s physical properties: it will raise the boiling point and it will lower the specific heat. These two changes actually work against each other. Raising the boiling point will make the water boil slower.
Does water boil faster with a lid?
So put a lid on the pan. The air in the pan will heat up as the water heats up, and it circulates back into the water as it’s heated. This helps bring the water to 212 degrees F more quickly.
How do I calculate how much heat I need?
To calculate the energy required to raise the temperature of any given substance, here’s what you require:
- The mass of the material, m.
- The temperature change that occurs, ΔT.
- The specific heat capacity of the material, c (which you can look up). …
- Here is a source of values of c for different substances:
- Q=m×c×ΔT.
What is water heat capacity?
Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.
How many kWh does it take to boil water?
Based on the above answers and examples, to boil 1 litre of water from 20C to 100C, requiring 0.183 kWh of either electricity or gas, at todays energy prices GAS is 68% cheaper than electricity.
