What does permeability mean in environmental science?

Permeability in fluid mechanics and the Earth sciences (commonly symbolized as k) is a measure of the ability of a porous material (often, a rock or an unconsolidated material) to allow fluids to pass through it.

What is soil permeability?

Soil permeability is the property of the soil to transmit water and air and is one of the most important qualities to consider for fish culture. A pond built in impermeable soil will lose little water through seepage.

What is meant by permeability biology?

Biology definition: Permeability is the state, condition, or property of a material (such as a biological membrane) to allow the passage of molecules through it. In a living system, however, the passage of molecules across the membrane is regulated. Not all molecules can easily pass through.

What is permeable in the body?

A permeable surface allows materials like liquids to pass through — either in or out. Inside the body, the walls of cells are permeable membranes that allow fluids and nutrients to get in and nourish the cells.

What is permeability and how is it determined?

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.

What are the effects of permeability?

A number of factors affect the permeability of soils, from particle size, impurities in the water, void ratio, the degree of saturation, and adsorbed water, to entrapped air and organic material.

What is definition permeability?

Definition of permeability 1 : the quality or state of being permeable. 2 : the property of a magnetizable substance that determines the degree in which it modifies the magnetic flux in the region occupied by it in a magnetic field.
