GENERAL GEOLOGY

Detailed explanation-1: -Porosity is the percentage of void space in a rock. It is defined as the ratio of the volume of the voids or pore space divided by the total volume. It is written as either a decimal fraction between 0 and 1 or as a percentage.

Detailed explanation-2: -Porosity is determined by dividing the volume of voids by the total volume of a material to determine a percentage. For example, Porosity (%) = (Volume of Voids / Total Volume) x 100.

Detailed explanation-3: -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%.

Detailed explanation-4: -Porosity ( % ) = volume of gas extracted bulk volume of sample × 100. Bulk volume must be determined independently by another method, which generally involves applying Archimedes principle of displacement to the sample when totally submerged in mercury.

Detailed explanation-5: -Void ratio is usually defined as the ratio of the volume of voids to the total volume of soil solid. Porosity (n): Porosity is defined as the ratio of the volume of voids to the total volume of the soil. The relationship between void ratio and porosity are as follows: e = n 1 − n a n d n = e 1 + e.
