Calculate the drag coefficient (based on the frontal area) of the 2-dimensional wedge- shaped projectile shown in the figure below, moving at a Mach number of 1.8. The projectile's length (in the flow direction) is 1 m. State all assumptions. M = 1.8 P1 = 1 atm Supersonic projectile 10 10 Notes: Some useful information is provided on the following pages. If using tables, use the nearest tabulated value - do not interpolate. For air, R 287 J/kg.K and k = 1.4.
