Benzene gas (C6H6) at 1 atm and 77oF is burned during a steady-flow combustion process with 90 percent theoretical air that enters the combustion chamber at 77oF and 1 atm. All the hydrogen in the fuel burns to H2O, but part of the carbon burns to CO. Heat is lost to the surroundings at 77oF, and the products leave the combustion chamber at 1 atm and 1900 R. Determine
(a) The heat transfer from the combustion chamber
(b) The exergy destruction.
