8.1 Hydro Power Plant A hydro power plant has a maximum capacity of 500 MW and generates 2500 GWh of electrical energy per year. The height for power generation is 80 m and the isentropic efficiency of the turbines is 92%. Determine the mass flow rate at maximum capacity, the total amount of water running through the turbines per year, and the average mass flow rate (ignore kinetic energy). Also, determine the temperature change of the water.
