A vertical cylindrical packed bed comprises a cylindrical central core of radius RA packed with spherical particles of diameter 0.08 m surrounded concentrically with an annular region of outer radius Re which is packed with spherical particles of diameter 0.02 m. The porosities of the central bed and the annular bed are, respectively, 0.4 and 0.25. Calculate the ratio Re/RA for which the volume flow rate of a fluid through the central core equals the volume flow rate through the annular space when the flow of fluid through the bed is turbulent.
