How do I calculate a Heat Load/Water Flow?

A water systems heat load in Btu/h can be calculated as:

h = 500 q dt (1)
h = heat load (Btu/h)
q = water volume flow rate (gal/min)
dt = temperature difference (oF)

Example - Water Chiller Cooling
Water flows with 1 gal/min and 10oF temperature difference. The ton of cooling load can be calculated as:

Cooling load = 500 (1 gal/min) (10oF) / 12,000 = 0.42 ton
