The aerodynamic drag of a new sports car is to be predicted at a speed of 75 km/h at an air temperature of 25°C. Automotive engineers build a one-fifth scale model of the car to test in a wind tunnel. It is winter and the wind tunnel is located in an unheated building. The temperature of the wind tunnel air is only 5°C. a) Determine how fast the engineers should run the wind tunnel in order to achieve similarity between...

Automotive engineers plan to build a one-third scale model of a sports car and test it in a wind tunnel. The temperature of the wind tunnel is at 25°C. The drag force is measured with a drag balance and the moving belt is used to simulate the moving ground. If the sports car runs at 25°C, Wind tunnel test section L Fom Moving belt Drag balance Figure 4 Question 4 a) Propose the speed of the car that can be...
