Question

A porous hollow fiber is placed in the center of a large cylindrical glass tube filled with water. (This
arrangement is similar to a concentric tube in tube heat exchanger). Water containing a dissolved solute
(component A) enters the fiber lumen. A portion of solute A diffuses into the larger shell and the
remainder passes through the fiber. If the concentration of solute A leaving the other end of the fiber is
10% of the entering concentration, calculate the overall mass transfer coefficient. For this problem you
may assume the mass transfer coefficient is infinity.
Fiber dimensions: diameter = 400 microns Length = 20 centimeters
Volumetric flow rate = 1 ml/min
Concentration of solute A exiting the fiber is 10% of the solute concentration entering the fiber.
Calculate the overall mass transfer coefficient (Ko)
