This is a subjective question, hence you have to write your answer in the Text-Field given below Under constant drying conditions, a filter cake takes 6 hours to reduce its moisture content from 30% to 8% on wet basis. The critical moisture is 12% and the equilibrium moisture 4%, both on dry basis. Assuming the rate of drying in the falling rate period to be directly proportional to the free moisture content(linear), estimate the time required to dry the cake from 25% to 5% moisture on dry basis.
