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

use back pressure i.e static pressure to get different value of these variables for same RPM. hope u got my point. regards

Hi,

Thanks for reply. For NPSH, how to set the boundary condition at inlet and outlet. Any idea?

Thanks JSM
