03: The water in a large water dam is to be used to generate electricity by the installation of a hydraulic turbine. The elevation difference between the free surfaces upstream and downstream of the dam is 320 m. Water is to be supplied to the turbine at a rate of 8000 L/s. The turbine efficiency is 93 percent based on the net head, and the generator efficiency is 96 percent. The total irreversible head loss (major losses + minor losses) in the piping system including the penstock is estimated to be 7.5 m. Determine the overall efficiency of this hydroelectric plant, the electric power produced, and the turbine shaft power.
