Question

2. (35P) Gasoline fuel (CH) at 25°C is burned in a steady flow combustion chamber with air that also enters at 25°C. The required mass flow rate of the diesel fuel is 49.5 g/s. Calculate; a) Using conservation of atoms, find number of moles and a, b) stoichiometric AF (A/F) c) Air flow rate (g/s), c) calculate the exit temperature of the product gases for stoichiometric combustion..
