Pressure Drop Equation for Liquids:
Δ P = G × (Q / Cv)
2
Δ P = Pressure drop (psi)
G = Specific gravity of liquid at 60 °F
Cv = Flow coefficient factor
Q = Flow rate (GPM)

•
These curves are theoretical; actual results may vary depending on installation conditions and other variables. Use these values for reference only.
•
The above pressure drop charts are based upon 1/8" perforated screens and baskets handling clean water at 60 °F during ideal inlet and outlet conditions. Therefore, they
should only be used for estimation purposes.
•
For fluids other than water, multiply the pressure drop (Δ P) obtained from the charts by the specific gravity of the fluid in question.
•
For mesh lined screens, multiply the pressure drop (Δ P) obtained from the charts by the corresponding correction factor shown in the Cv correction table.
