The suction diameter of 60mm reads 2psi vaccum and 50mm diameter discharge with 250kpag. The suction water level is 5m above water pump center line and discharge water level is 25m above the pump center line. The total head loss at suction and discharge is 2m. If discharge is 0.01m3/s, find the horsepower needed to pump the water for 80% pump efficiency
