A Pelton wheel is to be designed to develop 735.5 kW at 400 r.p.m. It is to be supplied with water from a reservoir whose level is 250 m above the wheel through a pipe 900 m long. The pipeline losses are to be 5 percent of the gross head. The coefficient of friction is 0.005. The bucket speed is to be 0.46 of the jet speed and efficiency of the wheel is 85%. Calculate :
(i) Pipeline diameter,
(ii) Jet diameter, and
(iii) Wheel diameter
