WebExample - Flow Coefficient Liquid. The flow coefficient for a control valve which in full open position passes 25 gallons per minute of water with a one pound per square inch pressure drop can be calculated as:. C v = (25 gpm) (1 / (1 psi)) 1/2 = 25 Flow Coefficient - C v - for Saturated Steam Since steam and gases are compressible fluids, the formula … WebAug 21, 2012 · Tonnage is calculated as follows: GPM x ∆ T︒ ÷ 24. For example, if the chiller has a flow rate of 550 GPM and the Delta T is 4.8〫F, then the tonnage would be 110 Tons. The part that you need to find out is what the pressure drop through the evaporator is at design.
