Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, ... Typical bulk density of clay soil is between 1.1 and 1.3 g/cm 3. This calculates to a porosity between 0.58 and 0.51. This seems counterintuitive because clay soils are termed heavy, ... 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 … See more Used in geology, hydrogeology, soil science, and building science, the porosity of a porous medium (such as rock or sediment) describes the … See more Casting porosity is a consequence of one or more of the following: gasification of contaminants at molten-metal temperatures; shrinkage that takes place as molten metal … See more • Void ratio • Petroleum geology • Poromechanics • Bulk density • Particle density (packed density) 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 … See more The ratio of holes to solid that the wind "sees". Aerodynamic porosity is less than visual porosity, by an amount that depends on the constriction of holes.
