In the far west states of the country, one can find wind farms with wind turbines that turn in response to a force of high-speed air resistance, r = ½drhoav2. the power available is p = rv = ½drhoπr2v3, where v is the wind speed and we have assumed a circular face for the wind turbine of radius r. take the drag coefficient d = 1.00 and the density of air as 1.20 kg/m3.(a) for a wind turbine having r = 1.30 m, calculate the power available (in kw) for a velocity of v = 8.40 m/s.(b) for a wind turbine having r = 1.30 m, calculate the power available (in kw) for a velocity of v = 25.5 m/s.
