Not if you look at the sample sentence provided at that link: Democrats faired marginally better in the study, ringing in at 31 percent.. I believe that using that sentence is an error on dictionary.com's part.
Porosity and Permeability Lab. The terms porosity and permeability are related. ï· porosity â the amount of empty space in a rock or other earth substance; this empty. space is known as pore space. Porosity is how much water a substance can hold. Porosity is usually stated as a percentage of the materialâs total volume. ï· permeability â is how well water flows through rock or other earth substance.
In multiphase flow in porous media, the relative permeability of a phase is a dimensionless measure of the effective permeability of that phase. It is the ratio of the effective permeability of that phase to the absolute permeability.It can be viewed as an adaptation of Darcy's law to multiphase flow.For two-phase flow in porous media given steady-state conditions, we can write. where is the flux, is the pressure drop, is the viscosity.t is the ratio of the effective permeability of that phase to the absolute permeability.
