Question

The water in a large lake will be used to generate electricity by installing a hydraulic turbine generator in a place where the water depth is 50 m. The water must be supplied at a rate of 5000 kg / s. If the electrical energy generated is measured in 1862 kW and the generator efficiency is 95%,

Determine:

(a) Overall efficiency of the turbine generator.
(b) mechanical efficiency of the turbine
(c) shaft power supplied by the turbine to the generator.

Please show all of the steps and calculations, as well as any assumptions made (if applicable).
