Yesterday, the temperature measured at a student apartment complex near Railroad Avenue in

Tallahassee was $32C,$ and the barometric pressure was recorded as $750mmHg$ and the relative

humidity was $80\%.$ The air conditioner in one of the apartments draws outside air and cools it to $18C$

and delivers it at a rate of $15,000\frac{L}{h}.$

$($a$)$ Sketch and label the humidifier completely showing all the known and unknowns, inlet and

outlet streams and mole fractions $($remember basis!$)$

Calculate the following:

$($b$)$ Saturated vapor pressure of water at $32C$

$($c$)$ Saturated vapor pressure of water at $18C$

$($d$)$ Molar flow rate of the outlet air

$($e$)$ Mole fraction of water in the inlet air

$($f$)$ Mole fraction of water in the outlet air

$($g$)$ Moles of wet air going into the system

$($h$)$ Moles of moisture condensed

$($i$)$ Rate of moisture condensation in $k\frac{g}{h}$

$($j$)$ Volumetric flow rate of air drawn from outside
