Liquid ethanol (C2H5OH) at 25C, 1 atm enters a reactor
Chapter 13, Problem 13.84(choose chapter or problem)
Liquid ethanol (\(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\)) at \(25^{\circ} \mathrm{C}\), 1 atm enters a reactor operating at steady state and burns completely with 130% of theoretical air entering in a separate stream at \(25^{\circ} \mathrm{C}\), 1 atm. Combustion products exit at \(227^{\circ} \mathrm{C}\), 1 atm. Heat transfer from the reactor takes place at an average surface temperature of \(127^{\circ} \mathrm{C}\). Determine
(a) the rate of entropy production within the reactor, in kJ/K per kmol of fuel,
(b) the rate of exergy destruction within the reactor, in kJ per kmol of fuel. Kinetic and potential energy effects are negligible. Let \(T_{0}=25^{\circ} \mathrm{C}\).
