The flow of a river is 4.25 m/s at a site where a 22.86 m hydrostatic head can be created by the erection of a dam. What is the potential capacity of a hydro-electric power plant if installed at this site? Consider that the hydraulic efficiency of energy conversion can be 80%, and that the electric efficiency can be 90%.

In a hydroelectric power plant, water flows from an elevation of 400 ft to a turbine, where electric power is generated. For an overall turbine–generator efficiency of 85 percent, Determine the flow rate of water if the irreversible head loss of the piping system between the free surfaces of the inlet and the outlet is 36 ft.
A site is being considered for wind power generation. At this site, the wind blows steadily at 9 m/s for 2,579 hours per year. Assuming the wind velocity is negligible at other times for simplicity, determine the kWh/year that can be produced at the site for a turbine with a mechanical efficiency of 100% and an effective flow area of 5 m2. Use a value of 1.25 kg/m3 for the density of the air. Give your answer in killowatt-hours per year (kWh/year). Hint: I reccomend starting by finding the kinetic energy (kJ/kg) of the wind. Hint 2: Multiply the power generation (kW) by the number of hours of wind per year (h/year) to get kWh/year.
Consider a river flowing toward a lake at an average velocity of 3 m/s at a rate of 500 m3 /s at a location 90 m above the lake surface. Determine the total mechanical energy of the river water per unit mass and the power generation potential of the entire river at that location.
In a hydroelectric power plant, water flows from an elevation of 400 ft to a turbine, where electric power is generated. For an overall turbine-generator efficiency of 82 percent, determine the flow rate of water to generate 100 kW of electricity if the irreversible head loss of the piping system between the free surfaces of the inlet and the outlet is 36 ft. Take the density of water to be p = 62.4 lbm/ft³. ft³/s. The flow rate of water is 0.151
