n-Octane gas (C8H18) is burned with 80% excess air in a constant pressure burner. The air and fuel enter this burner steadily at standard conditions and the products of combustion leave at 217°C. Calculate the heat transfer, in kJ/kg fuel, during this combustion. C8H18 25°C Lout Combustion chamber Products 217°C
