Answer Posted / ashish patel
npsh is the net positive suction head means that is the
actual head at the suction port because upto the suction
port the pressure of the fluid will be reduced due to the
vapour pressure acted on moving fluid so it's obvious that
the pressure at the suction port is reduced so reduced head
and it called npsh.
