When a batch of solids needs to be dried from 30% to 15% moisture content on a wet basis as shown in the picture below:

Q1) Make an expression or expressions for the rate of drying over the entire regine, using the data

Q2)Evaluate an expression for the time taken for drying the sample, then calculate this time taken for drying.

The initial weight of the wet solid is 1000 kg, and the unit surface area is 0.02 m/kg of dry weight of the sample. Falling rate Constant rate Trito ods Internal Unsaturated Surface drying 02
