Pore Space Definition

The term porosity is used in multiple fields including pharmaceutics ceramics metallurgy.

Pore space definition. The volume of such pores. Pore space pore space is defined in many different ways depending on whether you are a soil scientist geologist or an environmental engineer. Until very recently pore space was hardly considered a property right at all. In order to understand porosity better a series of equations have been used to express the quantitative interactions between the three phases of soil.

Strictly speaking some tests measure the accessible void the total amount of void space accessible from the surface. Meaning of pore space. Macropores or fractures play a major role in infiltration rates in many soils as well as preferential flow patterns hydraulic conductivity and evapotranspiration. Cross section of a typical soil with pore space in black.

This figure would lead to an under. Porosity or void fraction is a measure of the void 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. Pore space is defined by porosity of a material possessing free space between the mineral grains expressed as percentage rebollo et al 1996 and depends on size and sorting of the particles as a cubic or hexagonic package. Pore space the total continuous and interconnecting void space in the bulk volume of soil or rock.

There are many ways to test porosity in a substance or part such as industrial ct scanning. By convention the definition of pore space ex cludes fluid pockets that are totally enclosed within solid material vesicles or vugs for example that have no exchange with the pore space that has continuity to the boundaries of figure 1. Pore space in a soil may be of the following three types. The pore space of soil contains the liquid and gas phases of soil i e everything but the solid phase that contains mainly minerals of varying sizes as well as organic compounds.

What does pore space mean. The pore space in a soil represents that part of the soil volume which has been occupied by air or water. 0 geology all the pores in a rock. Pore space is generally thought of as a subsurface property right.
