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 much gas does it take to heat a gallon of water?
Heating a gallon of water by one degree Celsius requires around 8,337 BTUs (British Thermal Units) of energy. Since 1 cubic foot of natural gas produces about 1,031 BTUs, you would need roughly 8 cubic feet of natural gas to heat a gallon of water by one degree Celsius.
How many btus does it take to heat up one gallon of water?
It takes 8.33 BTUs to heat up one gallon of water by one degree Fahrenheit. The amount of energy needed to heat the water to a desired temperature will depend on the starting temperature and the desired final temperature.
How many BTUs does it take to heat 390 gallon tank of water from 60 degrees to 248 degrees?
To heat a 390 gallon tank of water from 60°F to 248°F, you would need approximately 1,251,600 BTUs. This calculation takes into account the specific heat capacity of water (1 BTU/lb°F) and the weight of water (8.34 lbs/gallon).
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 are in a gallon of propane?
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU burner, on high heat, it will last a bit over 4 and half hours of run time.
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
What is the BTU formula?
BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.
