Question $1.$

Propane $($C$\_(3)$H$\_(8))$ at $298$K$,1$atm, enters a combustion chamber operating at steady state with a molar

flow rate of $0\mathrm{.}7$kmo$($l$)/($s$)$ and burns completely with $200\%$ of theoretical air entering at $298$K$,1$atm.

Kinetic and potential energy effects are negligible. If the combustion products exit at $560$ K $,$

$1$ atm, determine the rate of heat transfer for the combustion chamber, in kW$.$
