A proposed hydro electric power plant as depicted is to be power by an impulse (Le. Pelton) tachine in which the electrical generator has an overall efficiency of 85% The total head available to the plant is 650m and the length of the penstock pipe is 5km of 1m diameter. The diameter of the wheel is 3m and the bucket angle is 5º and frictional losses are approximately 10% along the bucket. Assuming that the minor losses are negligible and that the fanning friction factor of the penstock pipe is 0.06. Determine: 4(A) The volumetric flow rate in the Penstock for maximum power transmission 4(B) The Jet Size for optimum power transmission power 4(C) The rotational speed of the wheel for maximum efficiency 4(D) With the aid of inlet and outlet velocity triangles, the hydraulic power extracted by the turbine 4(E) The available hydraulic power in the penstock pipe and deduce the Hydraulic Efficiency, Overall Efficiency and Extracted Power
