How many BTUs will it take to lower 1 gallon of water 1 degree?
Dermottusmc
1 BTU = heat corresponding to change in temperature of 1 pound of water by 1° Fahrenheit.
Weight of 1 gallon of water = roughly 8.33 pounds
Heat corresponding to change in temperature of 1 gallon of water by 1° Fahrenheit = 8.33 BTU.
But it doesn't take that, i.e. you don't have to supply it. You're talking about lowering the
temperature, so you're just allowing the water to cool on its own. As it does, it releases
8.33 BTU of heat, which you can then collect and take away to use somewhere else.

How many btus does it take to raise of 5 pounds of water to 5 degrees Fahrenheit?
25
How many btus must be removed from one pound of water at 200 for it to end up as ice at 30?
144
How many btus are needed to heat one lb of water one hundred degrees?
100 BTU if it's Fahrenheit
How many btu per hour would be produced in a 12-kW electrical heater?
There are at least 5 different definitions for slightly different BTUs. One of them says that 1 kWh = 3412.14 BTUs. Let's use that one. 1 kWh = 3412.14 BTUs 12 kWh = 40,945.68 BTUs
How many BTUs are needed to cool 500 sq ft?
12,000
How many BTUs will it take to change 1 gallon of water at 32 degrees to ice at 32 degrees?
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.
How many BTUs does it take to heat 390 gallon tank of water from 60 degrees to 248 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.
How many BTUs per gallon of petrol?
About 114,000 BTU per US gallon.
What is BTU of gasoline in engine?
BTU is an abbreviation for British Thermal Unit. This represents how much heat or energy is required to increase the temperature of 1 lb of water by 1 degree Fahrenheit. Gasoline, on average, creates between 115,000 and 125,000 BTUs. In contrast, ethanol creates about 75,000 BTUs.
How many BTU's per gallon of kerosine?
One gallon of kerosene will produce 134,000 BTUs of energy when burned.
What is the Gallon Per Hour use of a kerosene heater?
Depends on the BTUs of the heater.
How many BTUs does it take to heat one pound of water from 80 degree F to 212 degree F?
212 - 80 = 132 degrees temperature increase x 1 pound water = 132 BTU
How many btu's in office water-cooler?
There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the temperature of the water you start with and the temperature of the water comming out of the cooler you can calculate how many BTUs the cooling unit of the water cooler has removed. BTU=Temp1 - Temp 2 X LB water
How many btus does it take to heat up one gallon of water?
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.
How many btus are required to change one pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
1)This is a 5 part question. The first is realizing that 20F to 32F uses .5BTU per pound per degree. That means it takes 32-20=12*.5=6BTUs to get the ice to 32F. 2)Then you need to know the Latent Heat of Fusion for Ice which is 144BTUs (given). Lets assumes the ice changes from ice to water instantaneously at 32F. 3)Next we calculate the BTUs from 32F to 212F. Which is 1BTU per pound per degree F. 212-32=180 so it take 180BTUS. 4)Next we have to use the Latent Heat of Vaporization of water which will say instantaneously converts water to vapor. This takes 970BTUS (given). 5)Then we calculate the BTUS from 212F to 220F. Which is .5BTUs per pound per degree F which is 220-212=8*.5=4BTUs...... Finally add up all the BTUs and you get 6+144+180+970+4=1304BTUs.
How many btus does it take to raise half pound of water 1 degree?
One BTU is the energy required to raise one pound of water by one degrees. Therefore, your answer would be one half.
How Many BTU's per barrel of crude oil?
Approximately 5,800,000 BTUs per 42-gallon barrel.
