wind and power available in the rotor.
= 1.23 kg/m³, Power Coefficient, C,= 0.4, Calculate the power in the
2.A Site evaluated for a wind farm is observed to have steady winds at a speed of 8.5m/s.
Determine the wind energy (a) per unit mass, (b) For a mass of 10 kg and (c) For a flow
rate of 1154 kg/s of air.
3.The nominal power of the wind turbine is 3MW at wind speed 11.5m/s, generator
efficiency is 94%, gear box efficiency is 0.75, power coefficient of blades is 0.59. What
would be the diameter of the rotor?
