Question:

Gaseous propane mixes with air, both supplied at 500 K, 0.1 MPa. The mixture goes into a combustion chamber and products of combustion exit at 1300 K, 0.1 MPa. The products analyzed on a dry basis are 11.42% CO2, 0.79% CO, 2.68% O2, and 85.11% N2 on a volume basis. Find the equivalence ratio and the heat transfer per kmol of fuel.
