Propane $(C_3{H}_8)$ is burned in a combustion chamber at a flow rate of $26\mathrm{.}00\frac{m^3}{m}in$ with $40\mathrm{.}0\%$ excess air. If the propane and air

streams enter the chamber at $20\mathrm{.}0C$ and $1\mathrm{.}25$atm $($absolute$),$ and the products leave the chamber at $270\mathrm{.}0C$ and $4\mathrm{.}80$atm

$($absolute$),$ what is the volumetric flow rate of product gas from the chamber? Assume $100\%$ conversion and ideal behavior. To

solve for the flow rate, first label the process flow diagram. Label any quantities as "unknown" if they are not given or implied

and "none" if the quantity is zero. Do not leave any blank spaces. Variable names are given for reference later.
