    I read on a name plate of pump, it ia written than npsh = 0.25 meter.
    What is the meaning of it.
    I understand that in any pump suction pr at the eye of imperller shall be greater than its vapour pr. and lower than atm.pr.
    How 0.25 m ask us that it is lower than atm pr. But greater than vapour pr.

      Thanks for the reply.
      What is H,
      Option 1. Is it only Discharge head. ( means pr. at the pump dicharge)
      Option 2. Total head ( Discharge head - suction head) .
