Question
Air consisting of 79% N2 and 21% O2 on a dry basis (when no water is present) contains water at its dew
point, but with only a microscopic amount of liquid water, enters a dehumidifier at 100 SCMH at a pressure
of 1.05 atm and a temperature of 80 F. The air exits the dehumidifier in stream 2 at 70 F, 1.0 atm, and
40% relative humidity. A pure water stream containing no amount of dissolved gases exits the bottom of
the unit in stream 3.
A) What is the molar flowrate of air entering the dehumidifier?
B) Before performing any further calculations perform a degree of freedom analysis and complete
initial material balance table
C) Complete the final Table.
D) What amount of water is removed per hour in stream 3?
E) Using an appropriate equation of state, determine the true volumetric flowrate of stream 1.
