I have an open drum filled with water, ±100lt and heating with a LP gas burner. How do I calculate the BTU/hr heating the water to say 100°C? I need a safety 'tilting valve to cut off the gas flow when tilting the drum?
A British thermal unit (BTU) is defined as the amount of heat required to raise the temperature of 1 pound of water by 1 degree Fahrenheit. To calculate the temperature of a water sample from the BTUs applied to it, you must know the weight of the water and its starting temperature. Y...
BTU, or the British Thermal Unit, is the amount of heat required to raise one pound of water one degree Fahrenheit. The British Thermal Unit measures the amount of heat, or thermal energy. Temperature is the level rather than amount of heat. Therefore, there is no formula to convert a Br...

Because the calorie (cal), while not the SI unit of heat, is derived from metric units and is fundamental in a way: It isthe amount of heatneeded to raise one gram of water at room temperature by 1 K or 1 °C. (A 1-degree change on the Kelvin scale is identical to a 1-degree...
Specific Heat Capacity (c here) of a substance is the heat required (q) to raise the temperature of 1 unit mass of that substance by 1 unit c=qmΔT Where ΔT is the change in temperature The more heat you require to change the temperature of one unit mass of a substance by one ...
Again, with a 164 g shot of PP, the calculations would be: 164 g/0.70 g/cm3 or 234 cm3 volume for PP. Add 10 % for safety = 257 cm3. Barrel size needed: 0.65 x = 257 cm3, x = 395 cm3. If you work with volumes for the screws available, you are done. If you need to ...
2,854,939 Btu/hour / 12,000 = 237.9 t of max cooling needed. Here's a visual of how that breaks down among components, systems, people and more. This chart shows the percentage of heat output in the example data center above.
