1. The difference in elevation between the source of water supply and the centerline of the base of the nozzle of a Pelton wheel is 382.78 m. The efficiency of the Pelton wheel is 80%. During a test, the pressure at the end of the nozzle was 3516 kPa when the flow was 1.26 m³/s. The inside diameter of the penstock is 762 mm. Compute the shaft power developed by the turbine.
