Cv is the flow coefficient of liquid, which means that 60oF per gallon (GPM) is 1 pound (lb / in2) of pressure precipitation flow.

Expressed in weight flow pounds / hour:

Formula: \(C_v = w / (500 (dp SG)^{1/2})\) (3)

among them:

w = water flow (lb/h)

SG = Specific gravity

dp = pressure drop (psia)
