5. A membrane process is being designed to recover solute A from a dilute solution where c1 = 2.0 x 10-2 kg mol A/m3 by dialysis through a membrane to a solution where c2 = 0.3 x 10-2 kg mol A/m3. The membrane thickness (L) is 1.59 x 10-5 m. The X distribution coefficient (K') is 0.75, and the diffusivity (DAB) in the membrane is 3.5 x 10-11 m2 /s. The mass transfer coefficients in the solution, kc1 = 3.5 x 10- 5 m/s; and kc2 = 2.0 x 10-5 m/s, respectively. Calculate the flux at steady state, and the concentrations at the membrane interfaces (cli, clis, c2i and c2is). = =
