Btu formulas for water

The British thermal unit (BTU or Btu) is a measure of heat, which is measured in units of energy. It is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. It is also part of the United States customary units. The modern SI unit for energy is the joule (J); one BTU equals about 1,055 J (varying within the range of 1,054–1,060 J depending on the specific definition; see below). WebApr 4, 2024 · Use the formula Q = M X C X ΔT where: Q = heat load in British Thermal Units per Hour (BTUH) M = flow in Gallons per Hour (GPM) C = specific heat of the fluid. (For water, 1 BTU per pound times 8.34 pounds per gallon times sixty minutes per hour or 500 BTU per gallon per hour) ΔT = temperature difference in degrees Fahrenheit
