Web15 okt. 2024 · NPSHa = Suction Pressure – Vapor Pressure NPSHa = 87.91 PSIA – 72 PSIA = 15.91 PSIA NPSHa is always expressed in head units. A PSI value can be converted to head feet using the following formula: Head = PSI x 2.31/SG The team knows that the pumped fluids have a specific gravity (SG) of 0.8. Therefore: Head = 15.91 PSI x … WebCHANGES THAT AFFECT NPSH. Source Liquid Level – Changes in the liquid level feeding to the pump will affect NPSH. A raised liquid level in the tank will increase NPSHA, while a lower than expected liquid level will cause NPSHA issues. Height of Source – Flooded suction applications, where sources located higher than the pump will increase ...
