200 kg of solids (on dry basis) is subjected to a drying process for a period of 5000 seconds. The drying occurs in the constant rate period with the drying rate as, N c = 0.5 × 10 -3 kg/m 2 .s. The initial moisture content of the solid is 0.2 kg moisture/kg dry solid. The interfacial area available for drying is 4 m 2 /1000 kg of dry solid. The moisture content at the end of the drying period is (in kg moisture/kg dry solid)
