A 500kWe wind turbinehas a blade diameter of 40 metres and reaches a peak efficiencyCp of 0.39 at a nominal wind velocityvn of 9ms-1 and TSR of8. Determine:
1. the blade tip rotational speed inrpm and in radians/second in this operating condition; and,
2. the value of Cp atthe rated wind velocity vr of 15ms-1
