FLOW
COEFFICIENT " cv " DEFINITION:
FLOW RATE in Gallons Per Minute of 60° F Water
with 1.0 Psi Pressure Drop Across Valve.
NOMENCLATURE:
d = Bore Diameter (Inch) (1)
K = Resistance Coefficient
Q = Rate of Flow (Gallons Per Minute)
D P = Pressure Drop (Psi)
r =Weight density Of Fluid (Pounds Per Cubic Ft)
NOTE:
(1) Bore Diameter as Per Asme B16.34
For 32" and Over Bore Diameter
Was Considered as Per Api 6d. |
