The pressure of the water at the base of a nozzle of a Pelton wheel is 4850 , and the velocity of water at the same point is 6 . The jet diameter is 20 cm, the velocity coefficient of the nozzle is 0.98, and the kN peripheral velocity coefficient Ø = 0.45. (a) If the efficiency of the wheel is 86 %, find the brake power. (b) If the pitch diameter of the wheel is 2.5 m, what should be the normal operating speed in rpm?
