Dear friends
For calculating the shutt of pressure
We we have pump curve
Pump end of curve quantity ftom H Q diagram +suction pressure
My question is
In some design i see theu consider the suction vessrl design pressure instead of suction pressure .
My second question
As you know in pump curve we have 3impeller
Dose it need to calculate the shutt of pressure with max impeller. Or normal impeller is ok

Thanks
