A cruise missile with an ideal ramjet engine is flying at Mach 4.0 at an altitude where the ambient temperature is 100K. Considerratio of specific heatsy =1.4 and specific gas constant R=287J/kgK If the stagnation temperature in the combustion chamber is equal to 2310K, the speed of the exhaust gases (in m/s) is
Correct : 1880 to 1881
