Question:

Air enters the diffuser of a ramjet engine at 50 kPa, 230 K, with a velocity of 480 m/s, and is decelerated to a velocity of zero. After combustion, the gases reach a temperature of 1000 K before being discharged through the nozzle at 50 kPa. Using IG model, determine
(a) The pressure (p) at the diffuser exit and
(b) the velocity (V) at the nozzle exit.
