Chapter 9, Problem 9.12P

A supersonic flow at $M_1=3,T_1=285\text{K}$, and $p_1=1\text{atm}$ is deflected upward through a compression corner with $0=\text{3}0.\text{6}°$ 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.
