Ahot-air dryer is used to reduce the moisture content of 2200 kg/min of soybeans from 0.18 w/w water to 0.13 w/w water. air is drawn from the atmosphere at 22°c, 760 mm hg, and 50% relative humidity ( 2 * 2 h o h o p p ). the air is heated and then passes through the dryer. the air leaves the dryer at 50°c and 15 mm hg (gauge). a sample of the air is drawn into a chamber and slowly cooled while keeping the pressure constant. a mist is observed to form on the mirror in the chamber at 35.5°c. a) what is the rate (kg/min) that water is removed from the soybeans? b) what is the volumetric flow rate of air entering the dryer to achieve this?
