Air flows from a reservoir in which the pressure is kept at 124 kPa through a convergentādivergent nozzle and exhausts to the atmosphere where the pressure is 101.3 kPa. Under these conditions, the nozzle is choked and the flow is subsonic on both sides of the throat. To what value must the pressure in the reservoir be increased so that there is a normal shock on the nozzle exit plane?
