Large wind turbines with blade span diameters ofover 100 m are available for electric power generation. Considera wind turbine with a blade span diameter of 100 minstalled at a site subjected to steady winds at 8 m/s. Takingthe overall efficiency of the wind turbine to be 32 percent and the air density to be 1.25 kg/m3, determine the electric power generated by this wind turbine. Also, assuming steady winds of 8 m/s during a 24-hour period, determine the amount of electric energy and the revenue generated per day for a unit price of $0.09/kWh for electricity.
