Here i am going to present a practical problem in front of you. All fellows and experts and senior members are specially requested to comment please???

Problem is?

1-How to calculate suction lift for deep well multistage turbine pump designed for lifting water from underground and upto what maximum depth it can take suction.
2-What will be the practical design of suction and discharge spool i mean if we want to commission such practical pump what would be the schematic of piping components.
3-In discharge spool whether NRV(Non return valve) would be placed before manual valve or after manual valve.

If any body has literature in any form regarding such problem please share.
