In a wood drier, the hot air must contain at least 2% by wt. water to prevent the wood from drying too rapidly and splitting or warping. The original fresh air feed contains 1% by wt. water. Wood is dried from 20% to 5% by wt. water. The wet air leaving the dried contains 4% by wt. water. Calculate the amount of wet air that must be returned to the drier if 1000 kg/hr of wet wood is dried.

2. Industrial humidifiers has two inlet streams – 1. liquid water and 2. drier air. The entering liquid water stream flows at 5.31 mol/min. The component flow rate of air in the drier air stream is 44.3 mol/min. The exiting streams consist of a wetter air stream and a liquid water stream. The exiting liquid water stream contains 34.5% of the entering liquid water. The outlet streams are in vapor liquid equilibrium at 42.8oC and 786 mmHg. a) Draw the...

Hot air containing 1 mole% water vapor flows into a textile dryer at 350°F and 6.2 psig at a rate of 30,000 ft3/hr, and emerges at 220°F and 1 atm absolute pressure (i.e., it is vented outside the building) containing 10 mol% H2O. Calculate the following:a. The mass flow rate of the entering hot air stream in lbm/hrb. The rate of evaporation of the water from the textiles in lbm/hrc. The volumetric flow rate of the emerging air stream in...
