Question: Air enters the diffuser of a ramjet engine at 25 kPa, 200 K, with a velocity of 3000 km/h, and is decelerated to a negligible

Air enters the diffuser of a ramjet engine at 25 kPa, 200 K, with a velocity of 3000 km/h, and is decelerated to a negligible velocity. On the basis of an air standard analysis, the heat addition is 870 kJ/kg of air passing through the engine. Air exits the nozzle at 25 kPa. Using the IG model, determine
(a) The pressure (p) at the diffuser exit, and
(b) The velocity (V) at the nozzle exit.
