An automobile moving through the air causes the air velocity (measured with respect to the car) to decrease and fill a larger flow channel. An automobile has an effective flow channel area of 3 m2. The car is traveling at 90 km/h on a day when the barometric pressure is 75 cm of mercury and the temperature is 30°C. Behind the car, the air velocity (with respect to the car) is measured to be 82 km/h, and the temperature is 30°C. Determine the power required to move this car through the air and the area of the effective flow channel behind the car.
