Air at $50\mathrm{.}0\%$ relative humidity is cooled isobarically at $1$atm absolute from $70\mathrm{.}0C$ to $25\mathrm{.}0C.$

a$.$ Estimate the dew point and the degrees of superheat of the air at $70\mathrm{.}0C.$

Dew point: $C$

Degrees of superheat: $C$

b$.$ How much water condenses $($mol$)$ per cubic meter of feed gas? $($See Example $6\mathrm{.}3-2)$

mol

c$.$ Suppose a sample of the $70\mathrm{.}0C$ air is put in a closed variable$-$volume chamber containing a mirror and the pressure is raised at constant temperature until a mist forms on the mirror.

At what pressure $($atm$)$ would the mist form? $($Assume ideal gas behavior.$)$
