Question: Consider a smooth isentropic compression turn of 20°, as in Fig. P9.144. The Mach waves thus generated will form a converging fan. Sketch this fan

Consider a smooth isentropic compression turn of 20°, as in Fig. P9.144. The Mach waves thus generated will form a converging fan. Sketch this fan as accurately as possible, using five equally spaced waves, and demonstrate how the fan indicates the probable formation of an oblique shock wave.
