Question

Answer(i) and (ii) 

The hydroelectric facility that has been proposed will consist of a turbine with an efficiency of 89.2%. The facility will be located at a vertical depth of 14.8 m below the riverbed. The river flows with the following properties: o hydraulic diameter of 6.25 m o slope of 0.031 o wetted perimeter of 12.2 m a Chézy coefficient of 4.85 m0.5 s-1. The density of the river water is 998.2 kg m, and the acceleration due to gravity is 9.81 m s2. Assuming that the turbine operates for 94.0% of the time and one year is approximately 3.1536 x 10 s, calculate: i. the mass flow rate of the river ii. the maximum energy that could be extracted annually from the river flow.
