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.
