In a horizontal axis wind turbine having a blade length of 2000 inches, the average wind speed is found to be 28.34 x 10 inch / min. The air density is given as 1255 g/m and the power coefficient is 0.4. (consider 1 inch=2.54 cm). Answer the following: a) What should be the power generation of wind turbine in MW? b) If the wind speed, air density and power coefficient remains the same, what will be the required rotor diameter for generating a power of 9.742 x 10- MW?
