Q.2. A Pelton wheel has a mean bucket speed of 15 m/s. The jet of water issued from a nozzle of 12 cm in
diameter impinges the bucket with a velocity of 40 m/s. If the buckets deflect the jet through an angle
of 165°, find the head and power generated by the turbine. Assume the hydraulic efficiency is 90% and
the mechanical efficiency is 85%. [50 Marks]
