) A brick of clay is being dried in a batch dryer using constant drying conditions. You have been asked to determine the amount of time it will take to dry the clay from a total moisture content of 0.6 to a free moisture content of 0.08. You are given the following information: 1. Previously, the drier was able to dry a piece of clay with a total moisture content of 0.64 in 8 hours and 80% of the drying occurred with a constant rate. 2. The equilibrium moisture content is 0.1. 3. The critical free moisture content is 0.15.
