Octane (C8H18) burns to completion with air in a piston–cylinder device. The mass of octane to be burned is 0.05 lbm, and the process occurs with 10% excess air. The process is assumed to be at constant pressure which is 2 atm, with the reactants initially at 1100 R. After the combustion process is complete, the products are cooled to 2200 R. The walls of the cylinder are maintained at 1800 R. Determine the amount of entropy generation during the process.
