Flow in Consolidated and Unconsolidated Sands

There is little that can be done to allow for (1), Schlichter(35) calculated that in an assembly of spheres the actual path was 

W = the velocity of flow in c.c./sec. Fanning s equation is derivable from an equation of turbulent flow 

Some typical permeability constants for the stream-line flow of gases and liquids through media such as have just been considered are presented in Tables 6-8. The data recorded in 

Substance Mean radius Porosity Hg/unit viscosity, when, in eq. (28), 2pKpi+p ) = l
