Q.7. A combustible mixture of carbon monoxide and air which is ( 10 ℅  ) rich is compressed to a pressure of (8.28 bar ) and a temperature of  ( 282 o C ). The mixture is ignited and combustion occurs adiabatically at constant volume

. When the maximum temperature is attained analysis shows  ( 0.22 kmol ) of  ( CO )

        present for (1 kmol )  of  (CO )  supplied. Show that the maximum temperature reached is ( 2695 o C ). (14)

Q.8. Show that the thermal efficiency of the dual combustion cycle depends on the compression ratio and the o the relative amounts of heat supplied at constant volume and at constant pressure.                (14 )
