A 3-jet pelton turbine is required to generate 10,000 kW under a net head of 400m. The blade angle at outlet is 15o and the reduction in the relative velocity while passing over the blades is 5% . If the overall efficiency of the wheel is 80% , Cv = 0.98 and speed ratio = 0.46, find (i) the diameter of the jet , (ii) the flow rate and (iii) the force exerted by a jet on the buckets.
