Example 6:- A certain material (100 kg dry solid) was dried under constant drying conditions, and it was found that 3hr are required to reduce the moisture content from 0.3 to 0.15 kg 1120/kg wet solid. How much longer would be required to reduce the moisture to 0.06 kg H20/kg wet solid. At equilibrium the wet solid weight was 101 kg. a- Assume that no constant-rate period is encountered. b- Assume that no falling-rate period is encountered.
