Permeability of a space means the ratio of the volume within that space which is assumed to be occupied by water to the total volume of that space.
Permeability means the property of a material which permits movement of water through the material.
Permeability of a space means the percentage of the volume of that space which can be occupied by water.
Examples of Permeability in a sentence
Permeability is sensitive to changes in the coarse pore fraction and is thus a means of assessing the degree of compaction of concrete.
Permeability shall be tested in a manner approved by the Engineer.
More Definitions of Permeability
Permeability means the capacity of an aquifer or confining bed to transmit water. It is a property of the aquifer or confining bed and is independent of the force causing movement.
Permeability means the rate at which water moves through a unit area of soil, rock, or other material at hydraulic gradient of one.
Permeability means the property of a soil horizon that enables the soil to transmit gases, liquid, or other substances.
Permeability means the rate at which a soil transmits water when saturated.
Permeability means the ease with which fluid can move through a material and is measured by the rate of flow in suitable units.
Permeability means the ease with which a porous material allows water and the solutes contained therein to flow through it. This is usually expressed in units of centimeters per second (cm/sec) and termed hydraulic conductivity. Soils and synthetic liners with a permeability for water of 1 x 10-7 cm/sec or less may be considered impermeable.
Permeability means the rate at which water moves through a saturated unit area of soil or rock material at hydraulic gradient of one, determined as prescribed in N.J.A.C. 7:9A-6.2 (Tube Permeameter Test), N.J.A.C. 6.5 (Pit Bailing Test) or N.J.A.C. 6.6 (Piezometer Test). Alternative permeability test procedures may be accepted by the approving authority provided the test procedure attains saturation of surrounding soils, accounts for hydraulic head effects on infiltration rates, provides a permeability rate with units expressed in inches per hour and is accompanied by a published source reference. Examples of suitable sources include hydrogeology, geotechnical, or engineering text and design manuals, proceedings of American Society for Testing and Materials (ASTM) symposia, or peer-review journals. Neither a Soil Permeability Class Rating Test, as described in N.J.A.C. 7:9A-6.3, nor a Percolation Test, as described in N.J.A.C. 7:9A-6.4, are acceptable tests for establishing permeability values for the purpose of complying with this ordinance.
