Extracted text: When humid air containing water vapour and air (21 vol.% 02 and 79% N2) is passed through a condenser, water vapour in the air is condensed. A condenser can condense 95 vol% of the water vapour entering the condenser. If the flow rate of the outgoing condensed water is 225 L/h, calculate a) the ratio between the humid air entering the condenser and that leaving the condenser b) the composition (in mole fraction) of the air leaving the condenser.
