The NPSH calculation, basically, is about the suction mechanism alone and has little to do with the pump. The machine operator, and/or their technician or contractor can conclude this calculation.
The Available NPSH (NPSHA): a proportion of how close the liquid at a given point is to blazing, thus to cavitation. Actually it is the supreme weight head less the fume weight of the fluid.
The Required NPSH (NPSHR): the head an incentive at the suction side (for example the bay of a siphon) required to shield the liquid from cavitation (gave by the producer).
