ME 212 HW 5 1) An internal combustion engine burns liquid octane (C 8 H 18 ) and uses 125% theoretical air. The air and fuel enter at 25°C, the products leave the engine exhaust port at 900° K. In the engine 85% of the carbon burns to CO 2 and the remainder burns to CO. The heat transfer from this engine is just equal to the work done by the engine. Determine: a. Power output of the engine if the engine burns 0.005 kg fuel/s. b. The composition and the dew point of the products of combustion.

Unformatted text preview: 2) A natural gas consisting of 80% methane and 20% ethane (on a volume basis) is burned with 150% theoretical air in a steady-state, steady flow process. Heat is transferred from the products of combustion until the temperature reaches 700°K. The fuel enters the combustion chamber at 25°C and the air at 400°K. Determine the heat transfer per kmol of fuel....
