Wet leather enters a continuous drier at 45% moisture (wet) and leaves at a rate of 200 lbs/h with a moisture content of 25% moisture (dry). Air at 140°F and 10% RH enters the drier, and leaves the drier at 120°F and 40% RH. Assume atmospheric pressure on both inlet and outlet. Vapor pressures of water at 120°F and 140°C are 87.55 mm Hg and 149.44 mm Hg, respectively. A.) What is the mole fraction of dry air in the air-water vapor mixture entering the dryer?
