Question

Consider a wind turbine with a blade span diameter of 131 m installed at a site subjected to steady winds at 6 m/s. By considering the efficiency of the wind-turbine and taking the overall efficiency of the wind turbine to be 44 percent and the air density to be 1.24 kg/m3, determine the electric power (kW) generated by this wind turbine to1 decimal place.
