Follow the standard energy balance steps to determine the water condensed and the heat removed

from a humid air stream. The feed stream contains $18wt\%$ water $($balance is air$),$ has a

temperature of $300C$ and a pressure of $1$atm. The exit gas stream is at $1$atm and $30C.$ The

exit vapor composition should be determined from the psychrometric chart $($saturated$).$ The heat

of vaporization of water at $30C$ is $43\mathrm{.}7k\frac{J}{m}ol.$

a$.$ Draw a picture and label appropriately $($Basis: $1k\frac{g}{s}$ feed$).$

b$.$ Perform a degree of freedom analysis.

c$.$ Write appropriate equations.

d$.$ Complete all material balances.

e$.$ Specify reference states.
