...2/ A plant wishes to dry a certain type of fiberboard. To determine drying characteristic, a sample of 0.3 × 0.3 m with edges sealed was suspended from a balance and exposed to a current of hot dry air. Initial moisture content was 75%. The sheet lost weight at the rate of 1 104 Kg/s unit the moisture content fell to 60%. It was established that the equilibrium moisture content was 10 %. The dry mass of the sample was 0.90 Kg.All moisture contents were on wet basis .Determine the time for drying the sheets from 75% to 20% moisture under the same drying conditions.
