Mass Transfer In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg) 8.89 6.89 8.25 10 8.89 6.89 8.25 10 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 1.24 1.94 1.04 0.54 1.24 1.94 1.04 ANSWER DOWNLOAD EXAMIANS APP
