Mass Transfer It takes 6 hours to dry a wet solid from 50% moisture content to the critical moisture content of 15%. How much longer it will take to dry the solid to 10% moisture content, under the same drying conditions?

Mass Transfer To increase the absorption factor, (where, G = gas flow rate, S = solvent flow rate) Increase both 'G' and 'S' Increase 'S' and decrease 'G' Increase 'G' and decrease 'S' Decrease both 'G' and 'S' Increase both 'G' and 'S' Increase 'S' and decrease 'G' Increase 'G' and decrease 'S' Decrease both 'G' and 'S' ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer The drying time between fixed moisture contents within the 'constant rate period' is proportional to (assuming that drying occurs from all surfaces of the solid) (where, T = thickness of the solid ) T √T T3 T1.5 T √T T3 T1.5 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If moisture content of solid on dry basis is X, then the same on wet basis is (X - 1)/X X/(X - 1) (X + 1)/X X/(X + 1) (X - 1)/X X/(X - 1) (X + 1)/X X/(X + 1) ANSWER DOWNLOAD EXAMIANS APP
