Determine, for the airflow through the frictionless and adiabatic converging-diverging duct of Example 11.8, the ratio of duct exit pressure to duct inlet stagnation pressure that will result in a standing normal shock at:
(a) x = +0.1 m,
(b) x = +0.2 m,
(c) x = +.4 m. How large is the stagnation pressure loss in each case?
