The suction diameter of 60 mm reads 2 psi vacuum and 50 mm diameter discharge with 250 kpag. The suction water level is 5 m above water pump centerline with friction head loss of 0.5 m at suction pipes and discharge water level is 25 m above water pump centerline and head los at discharge pipe is 3 m.

A flow rate of 3 m'/s of water is available at a height of I 10 m at a project site. Due to losses in the sup- ply line, the head available at the inlet to powerhouse is estimated to be only 101 m of water. The leakage losses in the powerhouse are negligible. Mechanical losses account for 150 kW. Frictional losses in the rotor blades may be taken as 250 kW. The exit velocity of water from the turbines is 4.5 m/s. Calculate the hydraulic, mechanical, and overall efficiencies of the plant. The specific weight of water may be taken as 9810 N/m.
