Air approaches a sharp \(15^{\circ}\) convex corner (see Figure 8.4) with a Mach number of 2.0 , temperature of \(520^{\circ} \mathrm{R}\), and pressure of \(14.7 \mathrm{psia}\). Determine the Mach number, static and stagnation temperature, and static and stagnation pressure of the air after it has expanded around the corner.
