As we explained in earlier chapters, the air resistance to the motion of a vehicle is something important that engineers investigate. The drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data generally is represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: F, where air resistance for a car that has a listed C, = drag coefficient (unitless) measured drag force (N) drag coefficient of 0.4 and width of 190 cm and height of 145 cm. Vary the air speed in the range of 15 m/s
d) The drag coefficient in aircraft industry affected by some parameters which are the speed of plane (v), the plane length (L), the air density (p). the air dynamic viscosity (H), and speed of sound (a). By using dimensional analysis, identify two non-dimension numbers in which the drag coefficient is a function of them and explain how these two will effect on drag coefficient.
