The airflow passes a twice-deflected surface. The free-stream Mach number, \(M_{1}\) is 2 at sea level, and the air flows along the path with a \(16^{\circ}\) deflection angle passes through a weak oblique shockwave; and then passes a convex corner back, where the surface is deflected back to horizontal, as shown in Figure 10.9.

a) What is \(v_{1}\) ?

b) Find the final Mach number \(M_{3}\).

c) Find the air speed \(v_{3}\).
