WebSuction head = h s = p s / ρg + v s2 / 2 g. From the definition of vapor pressure head, Vapor pressure head = h v = p v / ρg. In the simplest language, we can say, NPSH = Pressure head at the inlet or suction – vapor pressure head. Let’s see the formula or equation of NPSH, NPSH = hs – hv. Web26 mei 2024 · Net Positive Suction Head (NPSH) in centrifugal and positive displacement pumps For example, if you know the flow rate your application requires, you find the gallons per minute (or hour) rate along the bottom horizontal line of the curve and then draw a line up to the head/PSI you require. http://www2.udec.cl/~josefcastillo/informe-final.pdf descargar powerpoint por mediafire
