Consider a wind turbine with a blade span diameter of 120m installed at a site subjected to steady winds at 8.25 m/s. Taking the overall efficiency of thewind turbine to be 33 percent and the air density to be 1.25 kg/m3, determine the electric powergenerated by this wind turbine. Also, assuming steady winds of 8.25 m/s during a 24-h period,determine the amount of electric energy and the revenue generated per day for a unit price of$0.08/kWh for electricity.arrow_forward
