Transport of Liquids in Porous Rocks

The rate of transport of liquids in porous environment is crucial engineering problem. It has importance in many fields like chemical engineering, hydropedology, economic geology and also in building materials science. The intensity of a liquid transport in porous body can be analyzed be means of three concepts – sorptivity, permeability and diffusivity. The approaches applied in field of porous rocks are discussed. Water absorption coefficients of set of sedimentary rocks of wide porosity range were determined experimentally and the relationship between them and specific pore volume of rocks was found.
