Liquid propane (C3H8) enters a combustion chamber at 25°C

Chapter 16, Problem 35P

(choose chapter or problem)

Liquid propane \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)\) enters a combustion chamber at \(25^{\circ} \mathrm{C}\) at a rate of \(1.2 \mathrm{~kg} / \mathrm{min}\) where it is mixed and burned with 150 percent excess air that enters the combustion chamber at \(12^{\circ} \mathrm{C}\). If the combustion gases consist of \(\mathrm{CO}_{2}, \mathrm{H}_{2} \mathrm{O}, \mathrm{CO}, \mathrm{O}_{2}\), and \(\mathrm{N}_{2}\) that exit at \(1200 \mathrm{~K}\) and \(2 \mathrm{~atm}\), determine (a) the equilibrium composition of the product gases and (b) the rate of heat transfer from the combustion chamber. Is it realistic to disregard the presence of \(\mathrm{NO}\) in the product gases?
