Liquid octane (C8H18) enters a steady-flow combustion chamber at 25oC and 8 atm at a rate of 0.8 kg/min. It is burned with 200 percent excess air that is compressed and preheated to 500 K and 8 atm before entering the combustion chamber. After combustion, the products enter an adiabatic turbine at 1300 K and 8 atm and leave at 950 K and 2 atm. Assuming complete combustion and T0 = 25oC, determine
(a) The heat transfer rate from the combustion chamber
(b) The power output of the turbine
(c) The reversible work and energy destruction for the entire process.
