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 volume flow cubic meters / hour:

Formula: \(C_v = 11.7 q (SG / dp)^{1/2}\) (2)

among them:

q = water flow (m3/h)

SG = Specific gravity

dp = pressure drop (kPa)
