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. i,(mol dry air/h) 0.21 mol 0/mol 0.79 mol N/mol ng(mol H20/h) ng(mol 0h) ig(mol N/h) nglmol H20 (v)/h)
