Components of Hydroelectric Power Plant

A hydro electric power plant derives the energy from the force of fast moving water to harness energy. The demand for energy needs has impacted the environment resulting in global warming. Extensive use of non-renewable energy sources like petrol and diesel is the primary reason for environmental pollution. A major shift from non-renewable energy sources to renewable energy sources is the only solution to encounter the rising issue of environmental damage.

Pls answer thank you! At a proposed hydroelectric plant site, the average elevation of headwater is 600 m, the tailwater elevation is 480 m. The average annual water flow is determined to be equal to the volume flowing through a rectangular channel 4 m wide and 0.5 m deep and average velocity of 5.5 m/sec. Assuming that the plant site can develop if the hydraulic turbine that will be used has an efficiency of 80% and generator efficiency of 92%. Consider a headwork loss of 4% of the available head. Find the annual energy produce in kW.
Complete solution and correct units pls. Thanks
