b. The hydroelectric facility that has been proposed will consist of a turbine with an efficiency of 90.4%. The facility will be located at a vertical depth of 15.2 m below the riverbed. The river flows with the following properties: hydraulic diameter of 7.10 m o slope of 0.033 O wetted perimeter of 12.6 m a Chzy coefficient of 4.95 m0.5 s-1. The density of the river water is 998.2 kg m-3, and the acceleration due to gravity is 9.81 m s-2 Assuming that the turbine operates for 95.0% of the time and one year is approximately 3.1536 x 107 s, calculate: i. the mass flow rate of the river (5 marks) ii. the maximum energy that could be extracted annually from the river flow.
