Unformatted text preview: A reservoir has a water surface of 1200 acres and an available storage of 4000 million gal. The watcrshcd contributing to and including the reservoir covers 35 miz. The dam of the reservoir contains a hydroelectric turbine with an available head of 120 ft and a mechanical efficiency of 33%. If thc runoff of rainwater is 36 ina'yea: and the evaporation from the surface is S infycar, compute the average electrical Output of 1116 garterator, in kw, assummg that all the overflow goes through the turbine.
