A solid material with 15 wt.% water is dried to 7 wt.% water under the following conditions. Fresh air is mixed with recycled air and blown over the solid. Fresh air contains 0.01 kg moisture per kilogram of dry air and recycled air is part of the air leaving the drier contains 0.1 kg moisture per kilogram of dry air. Mixed air entering the drier contains 0.03 kg moisture per kilogram of dry air. • Compute the amount of water removed per 100 kg of wet material fed to the drier? • Compute the amount of dry air in fresh per 100 kg of wet material entering?
