Description: Absolute energy level in the inlet cross-section of the pump at the operating point above the level corresponding to the vapor pressure in relation to the NPSH reference level.; Name: nom NPSH
Description: absolute total inlet head above the head equivalent to the vapor pressure based on the NPSH at the operating point; Name: NPSH-nominal
Description: total inlet pressure required to ensure there is sufficient margin to maintain the minimum instantaneous inlet pressure with adequate margin above the minimum liquid vapour pressure expected; Name: net positive inlet pressure required
