The available head from reservoir level to the four nozzles of a twin-runner Pelton wheel is 305 m. The length of the supply pipe, or penstock, is 3 km with a friction factor f = 0.02 and ΣK = 2.0. The turbine develops 10.4 MW with an efficiency of 0.85. P

(a) If the head across the turbine is 95% of the available head, what is the diameter of the penstock?

(b) If Cv = 0.98 for each nozzle, calculate the diameter of each jet
