The three jet Pelton wheel is required to generate 10,000 kW under a net head of 400 m. The blade at outlet is 15° and the reduction in the relative velocity while passing over the blade is 5%. If the overall efficiency of the wheel is 80%, C = 0.98 and the speed ratio = 0.46, then find: (i) the diameter of the jet, (ii) total flow (iii) the force exerted by a jet on the buckets (iv) The speed of the runner.

The three jet Pelton wheel is required to generate 10,000 kW under a net head of 400 m.
The blade at outlet is 15° and the reduction in the relative velocity while passing over the
blade is 5%. If the overall efficiency of the wheel is 80%, C = 0.98 and the speed ratio =
0.46, then find: (i) the diameter of the jet, (ii) total flow (iii) the force exerted by a jet on
the buckets (iv) The speed of the runner.
