Pelton wheel is to be designed for a head of 400 m when running at 500 rpm. The Pelton wheel develops 10000kW shaft power. The blade angle at outlet is 15º. The relative velocity of water is reduced by 5% by moving over the buckets. Velocity of the buckets = 0.45 times the velocity of the jet, overall efficiency = 0.8 and coefficient of the velocity = 0.98. If the Pelton wheel is provided with three nozzle, find (i) The diameter of jet (ii) Total flow rate and the force exerted by a jet on the buckets

Question
A Pelton wheel is to be designed for a head of 400 m when running at 500 rpm. The Pelton wheel develops 10000kW shaft power. The blade angle at outlet is 15º. The relative velocity of water is reduced by 5% by moving over the buckets. Velocity of the buckets = 0.45 times the velocity of the jet, overall efficiency = 0.8 and coefficient of the velocity = 0.98. If the Pelton wheel is provided with three nozzle, find (i) The diameter of jet (ii) Total flow rate and the force exerted by a jet on the buckets
