Dividing both sides by A \ Delta x, while \ Delta x \ rightarrow 0, we have for 1 dimensional linear flow in a porous medium the relation
22.
To avoid restricting the highly sensitive roots of epiphytic orchids, we grow them in porous mediums such as bark chips, tree fern fiber and stones rather than soil.
23.
There is fluid movement in a porous medium due to differences in pore fluid pressure created by different pore volume strains associated with mechanical loading of the porous medium.
24.

25.
The governing equation of Hele-Shaw flows is identical to that of the inviscid potential flow and to the flow of fluid through a porous medium ( Darcy's law ).
26.
Yet photography, which was itself excluded from the company of art for years, is such a porous medium that commercial work crossed the boundaries even in the early years.
27.
Mass conservation of fluid across the porous medium involves the basic principle that mass flux in minus mass flux out equals the increase in amount stored by a medium.
28.
A kinetic model based on experimental data can capture most of the essential transformation in diagenesis, and a mathematical model in a compacting porous medium to model the dissolution-precipitation mechanism.
29.
The formulation is based on Muskat's theory that the porous medium has a local structure of macroscopic size that is defined by the saturations, or volume fractions, of the fluid mixture.
30.
Constructed wetlands generally fall into two categories : those with water flowing over soil at shallow depths and those with water flowing through a porous medium, such as gravel, below the surface.
