Liquid under

The property of the material to pass through your body and pores air, gas, water or steam, is called air, gas, steam and water permeability. The penetration of water and other liquids occurs either due to capillary absorption, or due to the pressure difference on one and the other side of the material; For example, in the pipes through which the liquid under pressure flows, this liquid seeks to get through the walls out. Gas and air also penetrate due to the difference in pressure that occurs for various reasons.
