Conversion Between Head and Pressure | Neutrium
Conversion Between Head and Pressure | Neutrium

This article presents the method to convert between ,pressure, and ,head, for several common unit sets. ,Head, relates the ,pressure, of a fluid to the height of a column of that fluid which would produce an equivalent static ,pressure, at its base. It is particularly useful for the specification of pumps as it provides a measure of ,pressure, as it is independent of fluid density.

What is NPSH? | Pumps & Systems

It can be calculated by measuring suction ,pressure, at the ,pump, suction nozzle, cor­recting to datum, adding atmospheric ,pressure,, adding velocity ,head, and subtracting vapor ,pressure,. In equation form: NPSHA = P sg + P z + P atm + P vel - P vap. Where: NPSHA = ,NPSH, available to the ,pump,, psi. P sg = Gauge ,pressure, measured at suction nozzle, psig
