Question: Wet leather containing 61% water enters a continuous tunnel dryer and leaves at a rate of 485lb m /h containing 6.0% water. Dry air enters

Wet leather containing 61% water enters a continuous tunnel dryer and leaves at a rate of 485lb_m/h containing 6.0% water. Dry air enters the dryer at 140°F and 1 atm. and the outlet air is at 130°F and 1 atm with a relative humidity of 50%. Calculate the rate at which wet leather enters the dryer and the volumetric tow rate of the inlet air (ft³/h).
