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.
These rocks often have high porosity, and are usually âhigh permâ too. Porosity and permeability are absolutely necessary to make a productive oil or gas well. The petroleum geologist must stay focused on the porosity and permeability of the prospective reservoir. Porosity consists of the tiny spaces in the rock that hold the oil or gas. Permeability is a characteristic that allows the oil and gas to flow through the rock. You need both porosity and permeability to make a producing oil or gas formation. Porosity. Porosity of a rock is a measure of its ability to hold a fluid. Mathematically, porosity is the open space in a rock divided by the total rock volume (solid + space or holes).
