I have some problem about how to calculate power for my system. i use water jet as prime mover to move the turbine. Here i give the spec of my system :-
Water Jet spec
1. Operation pressure = 40 bar
2. Suction Volume = 17litre/minutes
We know that to calculate power is equal H(head) x flow rate x g x Efficiency...But for my system i don,t know the best way to calculate power. If i used this spec to calculate power, the result that i get is to small. So hope you can help me to simplify this problem. Thank you.

Hydraulic HP = GPM x lb/gal x H x Specific Gravity/33,000
17 liters/min = 4.49 GPM = GPM
Lb per gallon for water = 8.33
40 bar = 580.15 psi = 1339 feet of liquid head = H
Specific Gravity = 1.0 for water
Hydraulic HP = 4.49 GPM x 8.33lb per gal x 1339 ft of liquid head x 1.0/33,000
Hydraulic HP = 1.52
BHP = Hydraulic HP/Eff.
