Se quema n-octano [C8H18(l)] en la cámara de combus- tión de presión constante del motor de un avión con 70 por ciento de exceso de aire, que entra a la cámara de combustión a 600 kPa y 327 °C. Se inyecta combustible líquido a 25 °C, y los productos de combustión salen a 600 kPa y 1 227 °C. Determi- ne la generación de entropía y la destrucción de exergía por unidad de masa de combustible durante este proceso de com- bustión.
