A Wet Solid Is Dried From 35 To 10 Per Cent Moisture Under Constant Drying Conditions In 18 Ks 5 H If The Equilibrium 1 (464.55 KiB) Viewed 58 times

A wet solid is dried from 35 to 10 per cent moisture under constant drying conditions in 18 ks (5 h). If the equilibrium moisture content is 4 per cent and the critical moisture content is 14 per cent, how long will it take to dry to 6 per cent moisture under the same conditions? Hint Draw the drying curve in such a way to verify that the required drying covers both constant rate period and falling rate period so that formula for total drying time will be used. Apply the formula to the first drying so that to determine the drying parameters m A Apply the same formula to the second drying using the determined parameter m and A, to determine the required drying time.
