Problem #2

Air at 80°F and 80% relative humidity are cooled to 51°F at a constant pressure of 1 atm. Use the psychrometric chart to calculate the fraction of water that condenses, and the rate at which heat must be removed to deliver 1,000 ft3 /min of humid air at the final conditions.

A humid air stream flows into a condenser that also compresses the air stream. The inlet air is a 80°C and 1 atm absolute pressure, and contains 9 mol% water. The temperature is decreased to 14.5°C and the total pressure is increased to 2.8 atm absolute, resulting in condensation and removal of some of the water as liquid. The air leaving the condenser/compressor is then heated at constant pressure to 100°C. Calculate (a) the fraction of the incoming water that...
