Default Pump characteristic curves
Posts: n/a
Dear all,

In water pump analysis, I am extracting the characteristics curve like Q vs H, Q vs Power and Q vs NPSH. I am new to this pump domain. How to set the boundary condition to extract these characteristic curves. The only input I have, is rotational speed of pump.

Please give your ideas and experience. It is more helpful to me.

Thanks in advance

With regards, JSM
