WebFeb 23, 2012 · Air permeability is defined as the volume of air in millilitres which is passed in one second through 10Os mm 2 of the fabric at a pressure difference of 10mm head of water. Air permeability of any material can be defined as the air passing at right angle through a known area of the specimen in a unit time under a prescribed air pressure ...

permeability - Wiktionary
WebPermeabilityis a propertyof a material that describes how densea magnetic fieldwould be if the same amount of currentwas passed through it. Permeability is measured in henries per metre(H/m) and its symbol is μ{\displaystyle \mu }. WebGAS PERMEABILITY CONSTANTS 2533 AP (7) Following the general rule of using the same unit of pressure in both pV and Ap, the units of P are given by (cm2/sec)(To/aT). Since (l/a-To/T) is a dimensionless number, P is essentially given in units of cm2/sec, and its numerical value differs from P expressed by the compos- ite units by a factor of (To/aT). WebOxygen permeability ( OP) is a parameter of a contact lens that expresses the ability of the lens to let oxygen reach the eye by diffusion. In soft contact lenses, it is dependent on the thickness of the lens and the material of the lens, especially concerning the water content. Because of this dependence on thickness, transmissibility level ... form wg005
