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.
The permeability factors of some substances change with rising or falling temperature, or with the intensity of the applied magnetic field. In engineering applications, permeability is often expressed in relative, rather than in absolute, terms. If Âµ o represents the permeability of free space (that is, 1.257 x 10-6 H/m) and Âµ represents the permeability of the substance in question (also specified in henrys per meter), then the relative permeability, Âµ r, is given by: Âµ r = Âµ / Âµ o
