Web1 feb. 2024 · Net positive suction head (NPSH) is a term used in hydraulic system design and, specifically, pump selection. NPSH measures the margin a working liquid has over its vapor phase transition. It provides a definition of the operating conditions that would lead to vapor transition (flashing) and enables us to avoid them, accordingly. Web6 dec. 2024 · As we defined above NPSH is Atmospheric pressure head + Static Head – Vapour pressure head at liquid.. In above sketch, static head is available head in meter, from pump suction nozzle to liquid high level.. Whereas Vapour pressure head h(vp) is liquid vapour pressure (p) divided by liquid density (ρ) and gravitational acceleration or … WebNPSH = net positive suction head at reference point (usually center line of the impeller), ft. Ha = absolute pressure of the suction vessel, ft. Hvpa = fluid vapor pressure at pumping temperature, ft. Hst = static head to suction reference point (usually center line of the impeller), ft.
