A supersonic air flow over the wedge shown in Fig. $3$ with upstream conditions of $70$ kPa and $260$ K and a Mach number of $3.$ The axis of the wedge is tilted $15\backslash$deg with respect to the horizontal upstream air flow, determine the downstream Mach number, pressure, and temperature above $($M$\_\{2\},$P$\_\{2\})$ and T$)$ the wedge and under GM$\_\{3\},$P$\_\{3\}$ and T$3).$
