$(40$ pts$.)$ Use Eqn. $8\mathrm{.}33$ to estimate the laminar flame speed of a laminar flamelet in a spark$-$ignition internal combustion engine for conditions shortly after the spark is fired and a flame is established. Assume that the fuel is gasoline $($RMFD$-303),$ the pressure is $12\mathrm{.}0$ atm $,$ the equivalence ratio is $1\mathrm{.}0,$ and the temperature is $540$ K $.$ Repeat the calculation for a condition with $15\%($by mass$)$ exhaust gas recirculation.
