tunnel drier is used to dry an organic paint pigment. 1000 lbs /hr of pigment containing 10% water is to be dried to 0.50% water. The pigment is passed counter current to air which enters at 760 mmHg, 140 degree F and 10% humidity. The leaving air is at 750 mmHg, 95 degree F and 70% humidity. Note: entering air @ 760 mmHg and 170 degree F , H = 0.012 lbs H2O / lbs dry air leaving air at 750mmHg, 95 degree F , H =0.026 lbs H2O / lbs dry air Determine the following: a. How many pounds of water are removed from 1000 lbs of pigment fed to the drier? b. How many pounds of air are entering the drier? c. How many pounds of air are leaving the drier? d. What is the volume (ft3) of air entering the drier
