1. A reaction type hydro-electric plant uses a 94% efficiency generator to produce its rated output of 45MW. It was observed during its operation that the mechanical loss is 6MW while the volume of water that drives the turbine is 5,800 m3/min. Also, from the penstock down to the turbine, 18% hydraulic head loss and 10% leakage loss occurs which are equally distributed and based on the parameters at the dam. Draw the schematic diagram and compute the following: 1) Percent mechanical loss, % 2) Gross Head, m 3) Power by the jet, kW 4) Mechanical Efficiency, %
