A missile with a Ramjet engine is flying in air. The temperature at the inlet and the outlet of the
combustor are 1200 K and 2500 K respectively. The heating value of the fuel is 43 MI/kg and the
burmer efficiency is 90%. Considering the working fluid to be air (Cr=1005 1/kgK and γ=1.4) the
fuel/air ratio (f=ms/mα) for this engine is equal to:
