  • How to calculate NPSHA in a closed pumping Loop? Pump ...

    Oct 25, 2007· In a closed circuit, sum of heads lost = pump head + initial head. You have to maintain a minimum (initial) head/pressure in the loop, such that you will not have NPSHR > NPSHA. So minimum initial pressure is the vapor pressure at the suction flange. You can use that as a reference point if you like and add or subtract all heads
