An air stream, with Ma $=2\mathrm{.}5$ and $68\mathrm{.}49$ kPa, is forced to rotate $8\backslash$deg by a ramp on the surface of a body. A weak oblique shock wave is formed, as seen in the figure. For k$=1\mathrm{.}4,$ calculate using exact oblique shock wave theory. a$)$ The angle of wave B$,$ b$)$ Sea $).$ Use your diagrams to estimate $($d$)$ and $($e$)$ p$2$
