A twin jet Pelton wheel is required to generate 7500 KW when the available head at a nozzle is 400 m. Assuming generator efficiency of 95% overall wheel efficiency of 80% , coefficient of velocity as 0.98, speed ratio as 0.46, reduction in relative velocity while passing through bucket as 15% and taking that the jet is deflected through 165 by the bucket, the diameter of each jet
