Wet solids containing 40% moisture by weight are dried to 10% moisture content by weight by passing moist air over the wet solids. The incoming air is at 93 °C and 800 mm Hg pressure and the partial pressure of water vapor in the entering air is 10 mm Hg. The exit air has a dew point of 60 °C. (a) How many kmols of incoming air at 93 C and 800 mm Hg must be used per 100 kg of wet solids entering?
