WebEffective Permeability. The ratio of the effective permeability (αD)eff,i for layer i, consisting of a dispersed (d) phase and a continuous (c) phase (as occurs in the alginate layers of the model system), to the permeability of the continuous phase (αD)c was calculated from Maxwell’s relationship:(28.9)(αD)eff,i(αD)c=2−2ϕ+ρ(1+2ϕ)2+ϕ+ρ(1−ϕ)where αD is the … Webothers, have also shown that as c increases the soils become more fine-grained.I Hence, as Ic increases the soil permeability (k) generally decreases. Figure 2 shows the range of k …

"The following table should be used with caution as the permeability of ferromagnetic materials varies greatly with field strength. For example, 4% Si steel has an initial relative permeability (at or near 0 T) of 2,000 and a maximum of 35,000 and, indeed, the relative permeability of any material at a sufficiently high field strength trends toward 1 (at magnetic saturation).
