Fresh air containing 4.00 mole% water is to be cooled and dehumidified to a water content of 1.70 mole% 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 2.30 mole% 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 the remainder is delivered to a room. Taking 100 mol of dehumidified air delivered to the room as a basis of calculation, calculate the moles of fresh feed, moles of water condensed, and moles of dehumidified air recycled.
Required:
a. Draw and label the diagram for this process.
b. For the system box consisting of the whole process, do a degree of into account quantities that you are asked for in the rest of this question. freedom analysis. How many degrees of freedom are there for this system
c. Calculate the moles of the fresh feed, the moles of water condensed.
