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/(X + 1) (X + 1)/X (X - 1)/X X/(X - 1) X/(X + 1) (X + 1)/X 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 9 10 1 8 9 10 1 8 ANSWER DOWNLOAD EXAMIANS APP
