Question: Air enters a convergingdiverging nozzle with low velocity at 2.0 MPa and 100C. If the exit area of the nozzle is 3.5 times the throat

Air enters a converging–diverging nozzle with low velocity at 2.0 MPa and 100°C. If the exit area of the nozzle is 3.5 times the throat area, what must the back pressure be to produce a normal shock at the exit plane of the nozzle?
