Figure 10.20 illustrates the dependence of the drag coefficient, C_{D} on M for three three-dimensional axisymmetric bodies (a circular cylinder, a sphere, and a sharp pointed ogive) for supersonic flow (M = v/c > 1). Consider an ogive with a diameter of 3 in traveling in the air at standard atmosphere at an altitude of 30,000 ft above sea level, at a speed of 3800ft/sec, as illustrated in Figure EP 10.18. (a) Determine the drag force acting on the ogive.
