4. Air at 90C and 1.00 atm (absolute) contains 10.0 mole% water. A continuous stream of this air enters a compressorcondenser, in which the temperature is lowered to 15.6C and the pressure is raised to 3.00 atm. The air leaving the condenser is then heated isobarically to 100C. Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100C, and the ratio of volume of outlet air at 100 C to the volume of feed air at 90C. Note: use 100mol as basis. [3 marks]
