A $25\%$ Methanol $($CH$3$OH$)$ and $75\%$ Benzene $($C$8$H$15)$ is burned with air at an equivalence ratio of $0\mathrm{.}88.$ Exhaust and inlet pressures are $101$ kPa. Write the combustion equation for: $($a$)1$ kmole of the fuel burned with dry air $($b$)$ and another combustion equation for $1$ kmole of fuel burned with wet air of $60\%$ relative humidity air. Then calculate: $1.$ Air$-$to$-$Fuel ratio $2.$ Dew point temperature for the exhaust gases if the inlet air is dry $3.$ Dew point temperature for the exhaust gases if the inlet air is wet as listed in $($b$).$
