WebOct 15, 2024 · 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 2.31/0.8 = 45.9 feet PumpWorks Helps Customers … http://extraconversion.com/pressure/feet-of-head/feet-of-head-to-pounds-per-square-inch.html
