Detailed explanation-1: -Permeability is a measure of the ease of flow of a fluid through a porous solid. A rock may be extremely porous, but if the pores are not connected, it will have no permeability.
Detailed explanation-2: -Permeability is a measure of the ease of passage of liquids or gases or specific chemicals through the material. Permeability is determined by applying a head and determining the depth of penetration or the amount of liquid or gas passing through the sample.
Detailed explanation-3: -For groundwater to be able to get into a rock with good porosity it must also have good permeability. For a rock to be permeable and for water to move through it, the pore spaces between the grains in the rock must be connected. Permeability is therefore a measure of the ability of water to move through a rock.
Detailed explanation-4: -Permeability describes how easily water can flow through the rock or unconsolidated sediment and how easy it will be to extract the water for our purposes.
Detailed explanation-5: -What does permeability mean? Permeability is the quality or state of being permeable-able to be penetrated or passed through, especially by a liquid or gas. The verb permeate means to penetrate, pass through, and often become widespread throughout something.
