WebPorosity definition, the state or quality of being porous. See more. Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure the "accessible void", the total amount of void space accessible from … See more In gas-liquid two-phase flow, the void fraction is defined as the fraction of the flow-channel volume that is occupied by the gas phase or, alternatively, as the fraction of the cross-sectional area of the channel that is … See more The ratio of holes to solid that the wind "sees".

Web3. True. Permeability and porosity are terms that refer to characteristics of the rock and underlying soils. Soils with little or no voids such as clay are defined as "tight" soils. These soils have low permeability and porosity, meaning that water and other substances have difficulty passing through them. 4. True.
