9.46 Air enters the diffuser of a ramjet engine at 25 kPa, 220 K, with a velocity of 3080 km/h and decelerates to negligible velocity. On the basis of an air-standard analysis, the heat addition is 900 kJ per kg of air passing through the engine. Air
exits the nozzle at 25 kPa. Determine
(a) the pressure at the diffuser exit, in kPa.
(b) the velocity at the nozzle exit, in m/s. Neglect kinetic energy except at the diffuser inlet and the nozzle exit.
