A smooth concave turn similar to that shown in Figure 8.2 turns the flow through a \(30^{\circ}\) angle. The fluid is oxygen, and it approaches the turn at \(M_{1}=4.0\).

(a) Compute \(M_{2}, T_{2} / T_{1}\), and \(p_{2} / p_{1}\) via the Prandtl-Meyer compression, which occurs close to the wall.

(b) Compute \(M_{2}^{\prime}, T_{2}^{\prime} / T_{1}\), and \(p_{2}^{\prime} / p_{1}\) via the oblique shock that forms away from the wall. Assume that this flow is also deflected by \(30^{\circ}\).

(c) Draw a \(T-s\) diagram showing each process.

(d) Can these two regions coexist next to one another?
