Question:

The drag coefficient for a cone can be defined as $C_{D}=D / q_{\infty} A_{b}$, where $A_{b}$ is the area of the base of the cone. For a $15^{\circ}$ half-angle cone, plot the variation of $C_{D}$ with $M_{\infty}$ over the range $1.5 \leq M_{\infty} \leq 7.0$. Assume the base pressure $p_{b}$ is equal to free-stream pressure.
