An engine burns liquid Octane $(C8H18$ and uses $120\%$ theoretical air. The air and fuel enter ar $25C,$ the

products leave the engine exhaust ports at $1000K.$ In the engine $80\%$ of carbon burns to $CO2$ and the

remainder burns to CO$.$ The heat transfer from this cylinder is just equal to the work done by the engine.

Determine:

$($b$)$ The power output of the engine if it burns $10kg$ of fuel per hour

$($b$)$ The volumetric analysis of products of combustion and the dew point temperature. Assume atmospheric

pressure to be $1$ bar.
