Abstract

This theoretical distribution, addressing those filter media with a random arrangement of pores, was given credence in Part I of this paper via results of extended bubble-point measurements. Here the distribution is given credence through showing that theoretical calculations of laminar flow permeability correspond to actual measurements. And, the meaning of the average size pore—deduced from permeability measurements—is explained in relation to the pore-size distribution.
