Question: a 110 scale model automobile is tested in a wind...

Question details
A 1/10 scale model automobile is tested in a wind tunnel under dynamically similar conditions. The prototype speed is 75km/h and the model drag force Fd is 300N. Find the corresponding prototype drag force and the prototype power required to overcome this drag. Hint; the model and the prototype have the same reynolds number and coefficient of drag Cd. Cd= Fd/ (0.5pV^2L^2)
