Aerospace Engineering > GATE 2020 > Ramjet Engines
The design flight Mach number of an ideal ramjet engine is 2.8. The stagnation temperature of air at the exit of the combustor is 2400 K. Assuming the specific heat ratio of 1.4 and gas constant of 287 J/(kg K) the velocity of air at the exit of the engine is _______ m/s (round off to one decimal place).
Correct : 1712.0 to 1719.0
