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 The operation involved when the soluble material is largely on the surface of an insoluble solid and is merely washed off by the solvent is called Decoction Percolation Elutriation or elution None of these Decoction Percolation Elutriation or elution None of these ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Acetone is to be removed from air in an isothermal dilute absorber using pure water as solvent. The incoming air contains 5 mole% of acetone (yin = 0.05). The design equation to be used for obtaining the number of trays (N) of the absorber is, N+2 = 6 log (yin/yout).For 98% recovery of acetone, the number of trays required is/are 8 1 10 9 8 1 10 9 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If moisture content of solid on dry basis is X, then the same on wet basis is X/(X + 1) X/(X - 1) (X + 1)/X (X - 1)/X X/(X + 1) X/(X - 1) (X + 1)/X (X - 1)/X ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Air initially at 101. 3 kPa and 40°C and with a relative humidity of 50%, is cooled at constant pressure to 30°C. The cooled air has a Higher relative humidity Higher absolute (specific) humidity Higher dew point Higher wet bulb temperature Higher relative humidity Higher absolute (specific) humidity Higher dew point Higher wet bulb temperature ANSWER DOWNLOAD EXAMIANS APP
