What is meant by permeability?
Permeability is the quality or state of being permeable—able to be penetrated or passed through, especially by a liquid or gas.
The verb permeate means to penetrate, pass through, and often become widespread throughout something.
Things that are permeable have different levels of permeability..
What is meant by high permeability?
Special case: high permeability metals. Relative permeability refers to a material’s ability to attract and conduct magnetic lines of flux. The more conductive a material is to magnetic fields, the higher its permeability. Most materials have μR near 1, including copper, and gold.
What does semipermeable mean?
: partially but not freely or wholly permeable specifically : permeable to some usually small molecules but not to other usually larger particles a semipermeable membrane.
What is the importance of 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. The more permeable the soil, the greater the seepage.
How do you calculate water permeability?
8.4. 2 Normalized water permeability. TMP = ((Pfeed + Pretentate) / 2 – Ppermeate) as the module average transmembrane pressure. TCF = (viscosity of water at measured temperature)/(viscosity of water @ 25°C) as temperature correction factor (see Appendix).
What is an example of permeable?
The definition of permeable is a material that allows liquids or gases to pass through. A cloth that liquids can pass right through is an example of something that would be described as permeable. … Rainwater sinks through permeable rock to form an underground reservoir.
What are the 3 types of permeability?

Is high permeability good?
The greater the permeability, the easier it is to extract oil from the rock. Rocks such as sandstone have a very high porosity and permeability and make a productive oil or natural gas well. Looking at the permeability of rocks is one way that geologists can determine where a good location for an oil well is.
What is absolute permeability?
[′ab·sə‚lüt pər·mē·ə′bil·ə·dē] (electromagnetism) The ratio of the magnetic flux density to the intensity of the magnetic field in a medium; measurement is in webers per square meter in the meter-kilogram-second system. Also known as induced capacity.
What is water permeability test?
Water permeability test determines the resistance of concrete against water under hydrostatic pressure. … This permeability test should be considered the dominant test to evaluate the case whereby concrete is subjected to hydrostatic pressure. Durability testing is important to determine the lifespan of your structure.
What is water permeability?
Permeability is the capacity of a rock layer to transmit water or other fluids, such as oil. … Relative permeability is a dimensionless ratio that reflects the capability of oil, water, or gas to move through a formation compared with that of a single-phase fluid, commonly water.
What causes permeability?
Vascular permeability can be influenced directly by molecules that cause the barrier to disintegrate, whether it is a transvessel pore or a junction that needs to be opened. The relative extent of permeability can also be indirectly regulated by the blood pressure and the resulting blood flow.
What is another word for permeable?
Similar words for permeable: absorbent (adjective) absorbent, penetrable (adjective) all (adjective) assimilative (adjective)
How do you use permeable in a sentence?
Permeable sentence examplesJacquerod and Perrot have found that quartz-glass is freely permeable to helium below a red-heat (Comet. … On the upheaval of such rocks above the sea-level, fresh water from rainfall began to flow over their exposed surfaces, and, so far as the strata were permeable, to lie in their interstices upon the salt water.More items…
What is the meaning of permeability in science?
The ability of a substance to allow another substance to pass through it, especially the ability of a porous rock, sediment, or soil to transmit fluid through pores and cracks. Geologic permeability is usually measured in millidarcies.
Why is Clay’s permeability low?
Clay textured soils have small pore spaces that cause water to drain slowly through the soil. Clay soils are known to have low permeability, which results in low infiltration rates and poor drainage. As more water fills the pore space, the air is pushed out.
What is permeability formula?
Magnetic Permeability Formula Magnetic permeability formula is given as; Magnetic permeability (u) = B/H. Where B = magnetic intensity and H = magnetising field. The SI unit of magnetic permeability is henries per meter (H/m) or newtons per ampere squared (N⋅A−2).
How do you find permeability?
Permeability is a property of the porous medium that measures the capacity and ability of the formation to transmit fluids….Permeabilityv = fluid velocity, cm/sec.d = tube diameter, cm.∆P = pressure loss over length L,μ = fluid viscosity, centipoise.L = length over which pressure loss is measured, cm.
