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 force excreted by the jet on buckets in tangential direction. 103.47 KN 163.21 KN 189.78 KN 1765.23 KN
