Windmills slow the air and cause it to fill a larger channel as it passes through the blades. Consider a circular windmill with a 5-m- diameter rotor in a 10 m/s wind on a day when the atmospheric pressure is 150 kPa and the temperature is 25°C. The wind speed behind the windmill is measured at 8.0 m/s. a) Determine the specific volume of the air. (15 points) b) Determine the diameter of the wind channel downstream from the rotor. (15 points) c) Determine the power produced by this windmill, presuming that the air is incompressible. (10 points) Flow channel W
