In a laboratory drying test with a solid material the following relation for the falling rate period was obtained dX dt = -0.8(X - 0.05) Where X is the moisture content on dry basis and t is the time in hours. The critical moisture content is 1.4 kg moisture per kg dry solid. Calculate the time required for drying the material from X₁=4.0 to X₂=1.4 and the equilibrium moisture content.
