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 1 10 8 9 1 10 8 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer A pure drug is administered as a sphere and as a cube. The amount of drug is the same in the two tablets. Assuming that the shape and size do not influence the mass transfer, the ratio of rate of dissolution in water at t = 0 for the cubic to spherical tablet is 0.54 1.04 1.94 1.24 0.54 1.04 1.94 1.24 ANSWER DOWNLOAD EXAMIANS APP
