Derive the expression of hydraulic efficiency of a Pelton turbine. Is it possible that the hydraulic efficiency of a Pelton turbine can be 100%? If yes, explain when it is possible The water is supplied to a single jet Pelton wheel from a reservoir 300 m above the centre of the nozzle. The supply pipe is 70 cm in diameter and 5.6 km long. The friction c-efficient for the pipe is 0.03. The jet has a diameter of 10 cm. The coefficient of velocity for the nozzle is 0.97. The velocity of buckets is 0.47 of the jet speed. The buckets deflect the jet through an angle 165. The relative velocity of water is reduced by 15% while passing over the buckets. If m = 12 and the mechanical efficiency is 88%, calculate (i) quantity of water, (ii) hydraulic efficiency, (iii) shaft power, (iv) speed of the wheel, (v) number of buckets.
