A wind turbine with an extraction ratio (torque power/drag power) of 1.34 rotates at 0.39 rad/s in a wind with velocity 20m/s. The disc area is 339 sq m and the torque generated is 817 kNm. Taking air density as 1.29 kg/m/m/m, calculate the advance angle at the blade tip, assuming flow arrives at the disc axially. Express your answer in degrees.
