power output versus velocity profile for a wind turbine is shown in the figure below. Assume the rotor diameter is 80 meters, the air density is 1.22 kg/m3, the cut-in speed is 4 m/s, the rated speed is 13 m/s and the corresponding rated (i.e., peak) power output is 1500 kW. Calculate the power coefficient when the wind turbine is operating at wind speed of 5 m/s, 10 m/s and 13 m/s.
