A supersonic flow at $M_{1}=3, T_{1}=285 \mathrm{~K}$, and $p_{1}=1 \mathrm{~atm}$ is deflected upward through a compression corner with $\theta=30.6^{\circ}$ and then is subsequently expanded around a corner of the same angle such that the flow direction is the same as its original direction. Calculate $M_{3}, p_{3}$, and $T_{3}$ downstream of the expansion corner. Since the resulting flow is in the same direction as the original flow, would you expect $M_{3}=M_{1}, p_{3}=p_{1}$, and $T_{3}=T_{1} ?$ Explain.
