How many BTUs does it take to heat a 1250 gallon pool of water from 50 degrees to 82 degrees?

The specific heat of water is 1 BTU per pound per degree Fahrenheit. There are 8.3378 lbs/gallon at 60 degrees, which equals 3251.742 pounds of water. The number of BTUs to raise it 188 degrees is then 611,327.496 BTUs.

You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.

91,333 BTUs in 1 gallon of propane

That will completely depend on how much water there is.

134,000 BTUs per gallon

About 114,000 BTU per US gallon.

BTU: British Thermal Unit, the amount of energy it takes to raise one pound of water one degree Fahrenheit. In this case 500g(x aproximatly 8 pounds per gallon) or 4000 pounds x 70(the difference from 5 degrees to 75 degrees), which equals 280,000 BTUS

jet fuel kerosene is about 126,000 BTU per US gallon

For regular gasoline, 125,000 BTU per US gallon

You can assume two temperatures, and calculate the amount of energy required to heat the water from one temperature to the other. Then convert that to BTU.

One gallon of kerosene will produce 134,000 BTUs of energy when burned.

100 BTU if it's Fahrenheit

Depends on the BTUs of the heater.

8.33 btu if the gallon is US measure, 10 btu if the gallon is british measure. A btu is the amount of heat required to raise 1 pound of water 1 degree fahrenheit at atmospheric pressure (14.696 psia).

That depends on what the starting temperature of the water is, and what temperature you want it to reach. If you expect to get a number, you must first give the necessary numbers.

6519.2 btus are required.

Depending on the fuel grade and blend, about 114,000 - 125,000.

One measure does not directly translate to another. A BTU is the amount of heat that it takes to raise the temp of one pound of water by one degree F. A burning match, and a burning fireplace may both be at 650 degrees, but the fireplace gives off more heat (more BTUs)

1 gallon of Propane ~= 4.23 lbs ~= 91500 Btus 1 lbs of Propane ~=22000 Btus 20 lb tank of propane holds approx 4 gallons of propane (approx 366000 BTUs) Hope this helps/

Assume the water is initially at 40 F and 14.7 psia. m = ( 1.0 gal ) ( 1.0 ft^3 /7.4805 gal ) ( 62.43 lbm / ft^3 ) = 8.346 lbm Q = Delta U = ( m ) ( Cv ) ( T2 - T1 ) Q = ( 8.346 lbm ) ( 1.00 Btu / lbm - Fdeg ) ( 200 F - 40 F ) = 1335 Btu <----------------

1 btu raises 1 lb water 1 degree F from 62 to 63 degrees. generally 1 btu/lb/degree F x 20 degrees F difference x 15 lbs = 300 btus specifically the heat of the liquid at 100F is 67.97 btus and at 120F = 87.92 btu 87.92 - 67.97 = 19.95 btu 19.95 x 15 lbs. = 299.25 btus to be more accurate

1 gallon of Propane ~= 4.23 lbs ~= 91500 Btus 1 lbs of Propane ~=22000 Btus 20 lb tank of propane holds approx 4 gallons of propane (366000 BTUs) Your grill will last 366000 BTUs/ Grill BTU output hrs

Approximately 5,800,000 BTUs per 42-gallon barrel.

One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.

BTUs to Evaporate One Pound of Water Quick Answer: Somewhere around 1000BTU/lb Long answer: It depends on the temperature of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are…
