Chemistry

Wet air containing 60.4 mol% of pure water at 82.5˚C is fed to adehumidifier at a rate of 185 mol/hr. Outlet of the dehumidifierconsists of 2 streams – one stream of drier air and the otherstream is pure liquid water. The outlet streams are in vapor-liquidequilibrium at 812 mmHg and 31.7oC.
a) Draw the process flow diagram, number the streams, and label thecomponents in each stream.
b) Find the component mole flow rates (mol/hr) exiting thedehumidifier.
c) If the temperature of the inlet wet air increases by 10oC, willthe molar flow rate of liquid water exiting the dehumidifierincrease, decrease, or stay the same? Justify your answer.
