An inlet stream of a condenser consists of humid air in which 80% of the water vapor in the air is condensed. The flow rate of the condensate is measured and found to be 150 L/h. Dry air may be taken to contain 21 mole% oxygen, with the balance nitrogen. a) Construct a flowchart of this process with the complete label. b) Perform the degree-of-freedom analysis. c) Given that the entering air contains 12.0 mole% of water, i. Re-construct a new labeled flowchart of this process. ii. Calculate the flow rate of the gas stream leaving the condenser, in mole/h, and the mole fractions of oxygen, nitrogen, and water in this stream.
