A stream of gas contains $80\%$ air by volume and the rest is $n-$hexane. The temperature and

pressure of this stream are $68\mathrm{.}74C$ and $2500mmHg,$ respectively.

$($a$)$ Investigate the condition of the $n-$Hexane vapor whether it is saturated or superheated?

$($b$)$ Using calculation, propose the temperature where $n-$Hexane start to condense, if the

pressure is maintained at $2500mmHg.$

$($c$)1000mo\frac{l}{h}$ of the above$-$mentioned gas will be cooled using a condenser to $40C$ at

constant pressure. Draw and label the process flow diagram completely.

$($d$)$ Referring to part $($c$),$ propose the percentage of $n-$Hexane that will become liquid. Show
