Humid air at 70.0 °C and 1.00 atm with 2.00 °C of superheat is fed to a condenser. Gas and liquid streams leave the condenser in equilibrium at 15.0 °C and 1.00 atm.

Use material balances to determine the following quantities for a basis of 100.0 mol of warm, humid air fed to the condenser.

Mole fraction of water in the feed:	mol H₂O (v) / mol
Mole fraction of water in the chilled air:	mol H₂O (v) / mol
Moles of dry air in feed:	mol
Moles of water condensed:	mol
Moles of water in feed:	mol
Moles of water in chilled air:	mol

Humid air is enclosed in a 5.00-liter flask at 40.0°C. The flask is slowly cooled. When the temperature reaches 20.0°C, drops of moisture become visible on the flask wall. Although the pressure in the flask changes when the temperature drops, it remains close enough to 1 atm for the psychrometric chart to provide a close representation of the behavior of the system throughout the process. Use a psychometric chart to determine the relative humidity, absolute humidity, and wet-bulb temperature of...
