Problem
A schlieren photograph of a supersonic tunnel with upstream Mach number M1=2.2 shows a straight attached shock making an angle β=35∘ with the incoming flow. Take γ=1.4.
((a)) Find the wedge angle θ that produced this shock.
((b)) Find the pressure ratio p2/p1 across the shock.
((c)) Find the downstream Mach number M2.
