Porosity - Wikipedia
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%.

What is Porosity, Types and Causes of Porosity - Geology Hub
Porosity refers to the amount of empty space or voids within a material or substance. It is often expressed as a percentage of the total volume of the material, with the remaining percentage being occupied by the solid material.
Porosity - an overview | ScienceDirect Topics
Porosity is the result of the random arrangement of organic macromolecules within coal. Total porosity of coal ranges from 0.02 to 0.2%, with no apparent trends with carbon content. Porosity is often subdivided into macropore (d =300A°), intermediate …

2021年6月26日 · Porosity (percentage of total pore space) is the volume of the soil occupied by pores. \[ \%P = \frac{V_p}{V_t} \times100 \nonumber \] Where %P is percent porosity; Vp is volume of pores; Vt is volume total (solids plus pores).
Porosity and Permeability: Definition and Types - GeologyHub.com
2019年2月10日 · Porosity is the percentage of the bulk volume of a rock or soil that is occupied by interstices, whether isolated or connected. Effective porosity is the percent of the total volume of a given mass of soil or rock that consists of interconnected interstices.
Characterization and Analysis of Porosity and Pore Structures
Three broad categories of measurements are typically made, (a) on core or crushed rock, (b) within the bore hole via well logging tools and (c) seismic. In this chapter we will briefly address only those methods used in (a) and (b) that lead to quantification of porosity or pore features.
Porosity - Energy Education
Porosity is the property of an object that expresses the total volume of empty or pore space in the material. For rocks that contain hydrocarbon resources, porosity measures the percentage pore space occupies in a rock. [2]
