Find out the expression for the specific speed of a water turbine in terms of H.P. developed, the speed and the head available. Further show that the specific speed of a Pelton wheel is 2450 d/D, where d and D are the diameter of jet and diameter of mean circle bucket of Pelton wheel in meters respectively. Assume that mean bucket speed = 0.46. Maximum efficiency = 0.88% and coefficient of velocity of jet = 1.

The original design of a hydraulic turbine has data as follows: flow rate of 1 cumex, effective head of 50 m, and runner diameter of 1.5 m. If the same turbine design is to be used in another application where the available flow is 2.5 cumex and effective head is 75 m, what would be the runner diameter (in meters) for this new application?
