How to Convert BTU to GPM | eHow

This unit of measurement is valid when considering either the amount of thermal energy absorbed in a heating process or the amount of energy rejected in a cooling process. The BTU/Hour measurement of a device is related to the gallons per minute of liquid flow in the device, and the two units of measurement can be derived from one another with ...

Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat rejection in cooling ...
