Air at 90 degrees C and 1 atm (absolute) contains 10.0 moles% water. A continuous stream of this air enters a compressor-condenser, in which the temperature is lowered to 15.6 degrees C and the pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to 100 degrees C. Calculate 1) the fraction of water that is condensed from the air (mol water condensed / mol water feed) and 2) the relative humidity of the air at 100 degrees C.

Question

Air at 90 degrees C and 1 atm (absolute) contains 10.0 moles% water. A continuous stream of this air
enters a compressor-condenser, in which the temperature is lowered to 15.6 degrees C and the
pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to
100 degrees C. Calculate 1) the fraction of water that is condensed from the air (mol water condensed /
mol water feed) and 2) the relative humidity of the air at 100 degrees C.
