are plotted versus Knudsen number in Figure 21.
Although only two values have been presented (one for a filter substrate and the other for ash layer permeabilities
) this new approach has significant implications within the automotive aftertreatment industry, and potentially in other industries as well.
The anomalous bodies have the permeabilities
of 3.56 and 4.79, respectively.

," Production Monthly, vol.
Table 3 shows the ratios of the experimental permeabilities
toward both gases for the formulated paints.
The relationship between saturated hydraulic conductivities and air permeabilities
obtained in situ, with exhumed samples tested on site and in the laboratory, has also been examined for soils of various textures (Loll et al.
where [k.sub.b] and [k.sub.g] are the brine and gas permeabilities
, the parameters A, B, and C are dependent on effective stress, [[phi].sub.g] is the porosity open for gas flow, which should be the same as the effective porosity, and [[phi].sub.b] is the porosity open for brine flow.
Areas of the mold cavity closest to the squeeze head of a high pressure molding machine will see lower permeabilities
than other areas because the sand is more closely compacted in that area as compared to other parts of the mold.
Similarly, the average permeabilities
of the 51- to 102-mm (2- to 4-in) samples and controls were 2,072 and 2,255 coulombs, respectively.

and Mercury Capillary Pressures," Journal of Petroleum Technology, vol.
The similarities in the dispersed-phase morphology and crystallinity of the two types of EVOH resulted in similar permeabilities
compared to the other compositions.
