A Pelton wheel, 2.45 m in diameter, operates under the following conditions:

Net head = 370 m; co-efficient of velocity: 0.98; speed ratio = 0.47; relative velocity of water at outlet = 0.90 times that at inlet; deflection of jet =160°; diameter of the jet = 0.88 m. Determine the following:

(i) The input power to the shaft, and

(ii) The Rpm. of the wheel.
