Permeability theory
WebPermeability has the dimension L2 and porosity is dimensionless; therefore, ( k / ϕ) 1/2 may be substituted for the radius in the capillary pressure equation ( Eq. (5.11)) and rearranged as follows: or (5.15) Alternatively, it may be derived from the Carman–Kozeny equation (5.16) where Kz =Kozeny constant L =length of the porous medium, cm WebPermeability theory suggests that safety in environments depends on how far and how easily one can perceive or move through environments. Parts of environments that limit …
