In summary, the presented method allows to estimate both cold flow and hot flow
permeabilities from samples easily prepared from a whole monolith.
In order to validate the experimental approach described above, the saturated water conductivity ([k.sub.w], m/s) of the 5 soils was first estimated from intrinsic
permeabilities obtained in the gas flow experiments using Eqn 8:
The hyaloclastites have generally higher porosities and
permeabilities than the basaltic lavas and intrusions.
* If
permeabilities over 120 are used in synthetic sands, the surface finish of the castings may not be acceptable.
In contrast, deck sections 5 (sprayed) had average
permeabilities of 1,397 and 1,977 coulombs for the 0- to 51-mm (0- to 2-in) and 51- to 102-mm (2- to 4-in) sections, respectively.
where [P.sub.b,M], [P.sub.c], and [P.sub.d] are the
permeabilities of the blend as calculated by Maxwell's law (Eq.
The unit developed was able to quickly determine
permeabilities as low as an equivalent air thickness of [S.sub.D] = 1500 m.
Furnish is only a factor in that different furnishes produce sheets of different
permeabilities under the same fabrication processes.
If the objective is to obtain tires with different
permeabilities of the innerliner compounds and the same rate of pressure loss (k), then K must be constant.
The foamed plaster process or permeable metalcasting plaster, has been designed to produce mold
permeabilities comparable to those obtained in the Antioch process, but without the autoclaving cycle.
The sample suite was chosen so that a wide range of matrix
permeabilities and pore sizes were investigated.
The samples with similar velocities and initial
permeabilities were selected for further testing to ensure that they are parallel.
