A basic liquid sizing eqtn.. is as follows:
Q = C
V
∆P / G
(1)
where:
Q
=
Capacity in gallons per minute
C
v
=
Valve sizing coefficient determined experimentally for
each style and size of valve, using water at standard
conditions as the test fluid
∆
P
=
Pressure differential in psi
G
=
Specific gravity of fluid (water at 60°F = 1.0000)
Thus, C
v
is numerically equal to the number of U.S. gallons of water at 60°F that will flow through the valve in one minute when
the pressure differential across the valve is one pound per square
inch. C
v
varies with both size and style of valve, but provides an
index for comparing liquid capacities of different valves under a
standard set of conditions.
To calculate the expected C
v
for a valve controlling water or other
liquids that behave like water, the basic liquid sizing equation
above can be re-written as follows
C
V
= Q
G
∆P
