Water is to be supplied at a rate of 5000 kg/s to a hydro-electric generator located at the bottom of a lake at a height h. If the efficiency of the turbine-generator is 75% and of the generator 95%; using the first law of thermodynamics calculate the following: the efficiency of the turbine, the height in meters needed to produce 2413.8 hp of electric power, and the shaft power supplied by the turbine to the generator in KW.
