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 3.5 m2. The car is traveling at 90 km/h on a day when the barometric pressure is 70 cm of mercury and the temperature is 20°C. Behind the car, the air velocity (with respect to the car) is measured to be 82 km/h, and the temperature is 20°C. Determine the power required to move this car through the air and the area of the effective flow channel behind the car. Flow channel = The power required to move the car through the air is The area of the effective flow channel behind the car is | kW. m²

Transcribed Image Text:Problem 02.124 - Car moving through air flow
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 3.5 m². The car is traveling at 90 km/h on a day when the barometric
pressure is 70 cm of mercury and the temperature is 20°C. Behind the car, the air
velocity (with respect to the car) is measured to be 82 km/h, and the temperature is
20°C. Determine the power required to move this car through the air and the area of the
effective flow channel behind the car.
