Air enters the diffuser of a ramjet engine (schematic shown below) at 6 Ibf/in.?, 420°R, with a velocity of 1800 ft/s, and decelerates essentially to zero velocity. After combustion, the gases reach a temperature of 2000°R before being discharged through the nozzle at 6 Ibf/in.2 Diffuser- Nozzle Flame holder

Question
Air enters the diffuser of a ramjet engine (schematic shown below) at 6 lbf/in.?, 420°R, with a velocity of 1800 ft/s, and decelerates essentially to zero velocity. After combustion, the gases reach a temperature of 2000°R before being discharged through the nozzle at 6 Ibf/in.2 Diffuser- Nozzle Flame holder On the basis of an air-standard analysis, determine: (a) the pressure at the diffuser exit, in Ibf/in.? (b) the velocity at the nozzle exit, in ft/s. Neglect kinetic energy except at the diffuser inlet and the nozzle exit. Assume combustion occurs at constant pressure and flow through the diffuser and nozzle is isentropic. AAA
