✦ Synopsis

THE flow of gases through porous media ls of importance in many operations of interest to the chemical engineer, and Dr. C~XAN has written a useful monograph on this rapidly developing ileld. Viscous flow through unconsolidated beds of "normal" or "abnormal" types is ilrst considered in the light of the Koseny equation, the latter type implying departure of flow behavlour from the equation owing to non-uniform pore texture and high tortuosity. The author then deals with departures from Poiseuille flow when the pore diameter is comparable with or less than the mean free path, and discusses slip and Knudsen flow : with sufficiently fine pores such types of
