permeability coefficient[‚pər·mē·ə′bil·əd·ē ‚kō·i‚fish·ənt] (fluid mechanics) The rate of water flow in gallons per day through a cross section of 1 square foot under a unit hydraulic gradient, at the prevailing temperature or at 60°F (16°C). Also known as coefficient of permeability; hydraulic conductivity; Meinzer unit. permeability coefficient
