In this training we are going to learn How to calculate GPM for FCU & AHU for chilled water system.
The GPM formula is derived from the equation of HEAT Formula : Q = mc∆T
Heat Formula:
When heat energy is added to a substance, the temperature will change by a certain amount. The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.
heat energy = (mass of substance)(specific heat)(change in temperature)
Q = HEAT
m = mass flow of water in (lb/hr)
c = specific heat of water
∆T = Temperature difference (F)
