Question

a dcv has a pressure drop of 374 psi across it when 10 gal/min of fluid is passing through it, what is the value of the valve's flow coefficient in units of gal/min/sqrt(psi). assume the fluid s.g. is 0.85.

Answer 1

The flow coefficient of a valve is a measure of its ability to flow fluid. It is calculated as follows:

Cv = Q / sqrt(delta P / SG)

where:

Q is the flow rate in units of gallons per minute (gal/min)

deltaP is the pressure drop across the valve in units of psi

SG is the specific gravity of the fluid

In this case, we have:

Q=10gal/min

deltaP=374psi

SG=0.85

Substituting these values, we get:

Cv = 10 gal/min / sqrt(374 psi / 0.85) = 4.08 gal/min/sqrt(psi)

Therefore, the value of the valve's flow coefficient in units of gal/min/sqrt(psi) is 4.08.
