The mach number of an ideal ramjet is 3.25 and the ambient temperature is 400°r. the flow rate of air through the engine is 100 lbm/sec. because of thermal limits of the materials, the burner exit total temperature is 3200°r. the heating value of the fuel is 17,900 btu/lbm. what are the developed thrust, fuel ratio and tsfc for this engine?

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
