The available power in a stream of wind of the same cross-sectional area as the wind turbine can easily be shown to be Available power in watts P pU3 Td where U is the wind speed in m/s p is the density of air in kg/m d is the rotor diameter in m - a. If the temperature is 0°C, and the air density p at 0°C is 1.2754 kg/m', the available power is 225 kW, and the wind speed...

2. A wind turbine has the maximum power output at the rated speed of 12 m/s and a rotor diameter of 82 meters. The cut-in and cut-out speeds for this type of wind turbine are 4 m/s and 23 m/s, respectively. The table below shows the annual wind data near a potential site for setting up a wind farm using this type of wind turbine and the power coefficient of the wind turbine at the specific wind speed. The air...
