Description: Pressure at the pump inlet port, including the pump acceleration pressure in the inlet, minus the vapor pressure, at the given fluid temperature; Name: Net positive entry pressure
Description: total pressure (including velocity pressure) at the pump inlet connection less the liquid vapour pressure at the present temperature of the liquid; Name: net positive inlet pressure
Description: PN (nominal pressure) is an alphanumeric variable for reference purposes, relating to a combination of mechanical and measurement properties of a pipe component. It comprises the letters PN followed by a dimensionless number (according to EN 1333/96.08); Name: Nominal pressure of the muffs, A2
