A detailed treatment has been given of radial transport in and through a hollow cylindrical membrane for two initial distributions of diffusant within the membrane of practical interest. Expressions are given for concentration distributions of diffusant and for unit length of membrane, amounts present, fluxes through radial planes, and amounts transported up to time t across those planes. Some consideration has been given to forward and reverse flow and to relations between flow quantities characteristic of those transports. © 1997 John Wiley & Sons, Inc.
