Question
Transcribed Image Text:Q3-A stream of humid air enters a condenser in which 95% of the water vapor in the air is condensed.
The flow rate of the condensate (the liquid leaving the condenser) is measured and found to be
225 L/h. Dry air may be taken to contain 21 mole% oxygen, with the balance nitrogen. Calculate
the flow rate of the gas stream leaving the condenser and the mole fractions of oxygen, nitrogen,
and water in this stream.
