This quantity is raised to the negative-three power in the Kozeny-Carman equation, which predicts the pressure drop of a fluid.
When the structures conferring this property are below 500 angstroms in length, this property can be measured by comparing its isotherm with a reference curve in the Broekhoff-de Boer method. This quantity is raised to the negative-three power in the Kozeny-Carman equation, which predicts the pressure drop of a fluid. A method of measuring this property that relies on the expansion of helium gas frequently overstates its value, and it can be analyzed via imbibition experiments. The effective form of this property is the difference between its total form and the storativity of the material, and geotechnical engineers use a related form of this quantity called the void ratio. Its vugular form occurs in rocks prone to dissolution, and the theoretical maximum for it is 46% in rocks with cubic grain packing. For 10 points, name this property that is the proportion of the volume of rock occupied by interstitial space, and that affects how fluids flow through rock.
