Hi, one more question to clarify:

Question

How can the mass transfer kc and ultrafiltration solvent flux be increased?

Select one:

a. Another stream of fluid can flow adjacent to the membrane to accumulate solute at the membrane surface

b. Another stream of fluid can flow perpendicular to the membrane to accumulate solute at the membrane surface

c. Another stream of fluid can flow through the membrane to transport away part of the polarised solute layer

d. Another stream of fluid can flow perpendicular to the membrane to transport away part of the polarised solute layer

e. Another stream of fluid can flow adjacent to the membrane to transport away part of the polarised solute layer

I'm sure whether cross-flow and perpendicular flow are the same thing. In this case, I'm sure the answer is either c or d, but difficult to predict the most accurate. Hope someone can clarify. Thank you.

Answer 1

Sorry I meant I'm not sure if cross-flow and perpendicular flow are the same thing.
