Valve Flow Coefficient for Liquid
Valve Flow Coefficient for Liquid Formulas
| \(\large{ C_v = Q \sqrt {\frac {\Delta p} {SG} } }\) | (US units) |
| \(\large{ K_v = Q \sqrt {\frac {\Delta p} {SG} } }\) | (SI units) |
Where:
\(\large{ C_v }\) = valve flow coefficient (US units)
\(\large{ K_v }\) = valve flow coefficient (SI units)
\(\large{ SG }\) = specific gravity of liquid (water at 60°F = 1.0000)
\(\large{ Q }\) = valve flow rate, Gallons per Minute
\(\large{ \Delta p }\) = valve pressure differential, PSI
