Differential Pressure
How do I calculate liquid flow given pressure differential across an orifice of a given diameter?
The liquid is water at room temperature. The orifice is 0.5" diameter about 6" long and is actually a flow switch with a pressure drop specification of 7 psi at 10 GPM. Pressure on the inlet side will vary from 20 to 40 psi. The outlet side is open to the atmosphere.
Easy
