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.
Best Answer: Permeability is a function of the amount of porespace in the rock and how interconnected the pore space is: granite and other intrusive igneous rocks have very interlocking grain structure and little pore space so low permeability.n metamorphic rocks the alignment of the platy minerals serves to further destroy permeability. Of the sedimentary rocks, shale or slate is least permeable (and thus forms good seals to oil and gas reservoirs), and sandstones and limestones most permeable.
