1. Wet air containing 60.4 mol% of pure water at 82.5ËšC is fedto a dehumidifier at a rate of 185 mol/hr. Outlet of thedehumidifier consists of 2 streams â€“ one stream of drier air andthe other stream is pure liquid water. The outlet streams are invapor-liquid equilibrium 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.
