In a test of rocket propellant performance, liquid hydrazine (N2H4) at 100 kPa, 25C, and oxygen gas at 100 kPa, 25C, are fed to a combustion chamber in the ratio of 0.5 kg O2/kg N2H4. The heat transfer from the chamber to the surroundings is estimated to be 100 kJ/ kg N2H4, determine the temperature of the products exiting the chamber. Assume that only H2O, H2, and N2 are present. The enthalpy of formation of liquid hydrazine is 50417 kJ/kmol.
