A ramjet operates by taking in air at the inlet, providing fuel for combustion, and exhausting the hot air through the exit. The mass flow at the inlet and outlet of the ramjet is 60 kg/s (the mass flow rate of fuel is negligible). The inlet velocity is 225 m/s. The density of the gases at the exit is 0.25 kg/m³, and the exit area is 0.5 m². Calculate the thrust delivered by the ramjet. The ramjet is not accelerating, and the flow within the ramjet is steady.
