Extracted text: A hot air tunnel dryer is used to dry a filter press cake of titanium dioxide. The entering air is prepared by recycling a portion of the air discharged from the drier with fresh air at 30°C and 1 atm. The fresh air contains 0.015 kmol water/kmol dry air. The resulting mixture contains 0.045 kmol water/kmol dry air and is heated to 120°C and fed to the drier. Twenty kilograms per hour of water is picked up from the material being dried. The outgoing air contains 0.089 kmol water/kmol dry air and is found to have a temperature of 75°C at 1 atm. Find the following:
