In the manufacture of an active pharmaceutical ingredient (API), the API goes through a final purification step in which it is crystallized, filtered, and washed. The washed crystals contain 49.5% water. They are fed to a tunnel dryer and leave the dryer at a rate of 155 kg/h containing 4.00%% adhered moisture. Dry air enters the dryer at 145"F and 1 atm, and the outlet air is at 105"F and 1 atm with a relative humidity of 40.0%%. Calculate the rate (kg/h) at which the API enters the dryer and the volumetric flow rate (ft3/h] of inlet air. API rate: kg/h Dry air in: ft3/h
