Dear friends,
For calculating the shut off pressure we have its pump curve.
The pump end-of-curve flow rate is seen in the H - Q diagram +suction pressure.
My questions are:
In some designs I have seen the suction vessel design pressure is considered instead of the suction pressure.
My second question
As you know, in the pump curve we have the impeller size noted.
Do we need to calculate the shut off pressure with max impeller? Or is the normal impeller OK?
Thanks
