Problem 2: : A converging-diverging nozzle with an exit to throat area ratio of 3.0 exhausts air from a large high-pressure reservoir to a region of back pressure pb. Under a certain operating condition, a normal shock is observed in the nozzle at an area equal to 2.2 times the throat area. What percent reduction in back pressure would be necessary to rid the nozzle of the normal shock?
