Calculate Net Positive Suction Head to prevent pump cavitation.
Use negative value for suction lift.
Net Positive Suction Head (NPSH) is the difference between the pressure at the pump suction and the vapor pressure of the liquid. NPSHₐ must be greater than the pump's required NPSHᵣ to prevent cavitation.
NPSHₐ = Hₐ + H₂ - Hᵥₚ - H𝒻Related Tools
