Question

5. Fresh air containing 3.5%(mol) water vapor is to be cooled and dehumidified to a water content of 1.5% H2O. A stream of fresh air is combined with a recycle stream of previously dehumidified air and passed through the cooler. The blended stream entering the unit contains 2.1% H2O. In the air conditioner some of the water in the feed stream is condensed and removed as liquid. A fraction of the dehumidified air leaving the cooler is recycled and a reminder is delivered to a room. Taking 200 mole dehumidified air delivered to the room as a basis of calculation. Calculate: A) Draw and label the chart b) Calculate the moles of fresh feed, moles of water condensed, and moles of dehumidified air recycled
