1. A Pelton wheel is supplied with a jet velocity 1.6 times greater

than the bucket velocity. The buckets rotate with diameter 2.2m

at 1100 rev/min. The water is deflected 165 degrees. Blade

friction coefficient, k, is 0.96. Determine the mass flow rate of

water needed to develop a shaft power of 2.5 MW. The

mechanical efficiency of the device is 78%.
