A precise answer would require knowing the ambient temperature, the temperature of the water at the start, and the conductive properties of the vessel containing the water.
To calculate the BTUs needed to raise the temperature of a 40-gallon water heater by 60 degrees Fahrenheit, you can use the formula: BTUs = gallons × temperature rise × 8.34. For a 40-gallon heater, it would be 40 gallons × 60°F × 8.34 BTU/gallon°F, resulting in approximately 20,016 BTUs. Therefore, it takes about 20,016 BTUs to achieve that temperature increase.
A romm 20x9 is 180 square feet. You will need 5000 to 6000 BTUs for this.
To heat one gallon of water by 50 degrees Fahrenheit, you need approximately 0.2 therms of energy. This is based on the fact that it takes about 8.33 BTUs to raise the temperature of one gallon of water by one degree Fahrenheit, totaling around 416.5 BTUs for a 50-degree increase. Since one therm is equivalent to 100,000 BTUs, the calculation gives you about 0.00416 therms per degree, resulting in roughly 0.2 therms for the total increase.
About 114,000 BTU per US gallon.
A gallon of fuel oil typically contains about 138,500 BTUs, while a gallon of propane provides approximately 91,500 BTUs. This means that fuel oil has a higher energy content per gallon compared to propane. Therefore, when considering energy output, fuel oil is more efficient in terms of BTUs per gallon.
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.
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.
A gallon of kerosene typically contains about 135,000 BTUs of energy. At a burn rate of 30,000 BTUs per hour, a gallon of kerosene would last approximately 4.5 hours (135,000 BTUs ÷ 30,000 BTUs/hour = 4.5 hours). However, actual burn time can vary based on factors such as efficiency and burner design.
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.
One gallon of kerosene will produce 134,000 BTUs of energy when burned.
Depends on the BTUs of the heater.
