A generator driven by a wind turbine is required to deliver 5 MW of power at the generator terminals. The turbine rotor is rotating about a horizontal axis and the tower height is (140 m). The rotor is designed to operate at a fixed rotational speed of 60 rpm. 1. If the turbine delivers its rated power at a wind average speed of 13 m/s, calculate the corresponding diameter of the rotor blade and its tip-speed ratio, assuming typical value for the overall efficiency a No = 0.2745 2. If the downwind velocity 3 m/s, calculate the power coefficient of wind turbine. A generator driven by a wind turbine is required to deliver 5 MW of power at the generator terminals.
