An ideal ramjet is flying at an altitude of 10 km with a velocity of 1 km/s. The ambient pressure is
0.25 bar and temperature is 225 K. The exhaust gases from the engine are optimally expanded and
leave the nozzle at 900 K. If the specific heat ratio (γ) remains constant, the specific thrust developed
by the engine is approximately
