Expansion of a gas mixture very slow reaction rate, estimate the temperature and velocity of the water-gas mixture at the discharge end of the nozzle in Example 23.5-3 if the reaction rate is very slow, use the following data' log₁₀ K₃ = –0.15, C_p,H2 = 7.217, C_p,CO2, = 12.995, C_p,_H2O = 9.861, C_p,CO = 7.932 (all heat capacities are in Btu/lb-mole ∙ F. Is the nozzle exit pressure equal to the ambient pressure?
