It is usually expressed in cm/s or m/day. Questions (365) Permeability - Science topic. Alternative definition of permeability. Magnetic permeability ( μ ) is the ability of a magnetic material to support magnetic field development. The concept of permeability is of importance in determining the flow characteristics of hydrocarbons in oil and gas reservoirs, and of groundwater in aquifers. It may also refer to the ease with which ions or molecules pass through the pore of channel proteins. Porosity and permeability Porosity and permeability are two of the primary factors that control the movement and storage of fluids in rocks and sediments. permeability 1. ~ Choose from 500 different sets of permeability earth science flashcards on Quizlet. If a substance is permeable, it allows liquids or gases to go through it: 2. Chemistry. Permeability is affected by the pressure in a rock. How to use permeable in a sentence. Permeability is the property of rocks that is an indication of the ability for fluids (gas or liquid) to flow through rocks. ē] (electromagnetism) A factor, characteristic of a material, that is proportional to the magnetic induction produced in a material divided by the magnetic field strength; it is a tensor when these quantities are not parallel. Permeability definition: the state or quality of being permeable | Meaning, pronunciation, translations and examples In this video I review the difference between permeability and porosity of rocks. ... you'll also get unlimited access to over 83,000 lessons in math, English, science, history, and more. Toggle navigation Menu. What does Permeability mean? Permeability definition is - the quality or state of being permeable. Units. Since permeability significantly influences the deterioration of concrete, it is necessary to take precaution to protect against water and chloride permeability to any materials to prevent corrosion and acceleration of the corrosion process. Permeability Definition - Permeability, as it pertains to soil, is a measure of the ability of a soil to allow water to flow through it. Permeability is another intrinsic property of all materials and is closely related to porosity. Persistence: Refers to the length of time a compound stays in the environment, once introduced. The permeability of free space, μ 0, is a physical constant used often in electromagnetism. Selective Permeability Definition and Examples Selectively Permeable Versus Semipermeable. The... Permeability Definition ... Mixing the Mud: The Science of Drilling Fluid in HDD. Meaning of Permeability. Permeability, also called magnetic permeability, is a constant of proportionality that exists between magnetic induction and magnetic field intensity. 2: the property of a magnetizable substance that determines the degree in which it modifies the magnetic flux in the region occupied by it in a magnetic field The SI unit for permeability is m 2.A traditional unit for permeability is the darcy (D), or more commonly the millidarcy (mD) (1 darcy 10 −12 m 2).The unit of cm 2 is also sometimes used (1 m 2 = 10 4 cm 2).. Definition: Permeability refers to the ease with which molecules cross biological membranes. Tom Grace, TERC. The coefficient of permeability variation described by Dykstra and Parsons [19] is also referred to as the permeability variation or permeability variance.This method assumes that vertical permeabilities in a reservoir will have a log-normal distribution. Learn permeability earth science with free interactive flashcards. Effective permeability is the ability to preferentially flow or transmit a particular fluid through a rock when other immiscible fluids are present in the reservoir (for example, effective permeability of gas in a gas-water reservoir). Permeability: The ability of a water bearing material to transmit water. The SI unit for permeability is m 2.A traditional unit for permeability is the darcy (D), or more commonly the millidarcy (mD) (1 darcy 10 −12 m 2).The unit of cm 2 is also sometimes used.. Microscopic structure of shale, sandstone, and limestone with water in pore spaces. It … Understanding Trenchless Lateral Rehabilitation. It is measured by the quantity of water passing through a unit cross section, in a unit time, under 100 percent hydraulic gradient. Permeable definition is - capable of being permeated : penetrable; especially : having pores or openings that permit liquids or gases to pass through. Applications. Permeability is a measure of the ease with which a fluid (water in this case) can move through a porous rock. […] ALFRED PASIEKA/SCIENCE PHOTO LIBRARY / Getty Images Science. If this permeability rate does not exceed 3 mm/h, you may consider this soil horizon as suitable for a pond bottom. Related glossary terms/phrases: Permeable Learn more. The unit of measure is called the darcy, named after Henry Darcy (1803–1858). Units. In other words, magnetic permeability is the constant in the proportionality between magnetic induction and magnetic field intensity. If the material has high permeability than pore spaces are connected to one another allowing water to flow from one to another, however, if there is low permeability then the pore spaces are isolated and water is trapped within them. If a substance is…. This lesson will provide you with a definition of selective permeability. Permeability definition: the state or quality of being permeable | Meaning, pronunciation, translations and examples They are intrinsic characteristics of these geologic materials. Since hydraulic gradient (i = Δh/1) has no units, permeability has the same units as that of velocity. Table of Content. The exploitation of natural resources, such as groundwater and petroleum , is partly dependent on the properties of porosity and permeability. High permeability will allow fluids to move rapidly through rocks. Also known as magnetic permeability. In other words, the magnetic permeability of a material can also be said to be its magnetization capability. Information and translations of Permeability in the most comprehensive dictionary definitions resource on the web. (hydraulic conductivity) In general, the ability of a rock, sediment, or soil to permit fluids to flow through it.More precisely, the hydraulic conductivity is the volume flow rate of water through a unit cross-sectional area of a porous medium under the influence of a hydraulic gradient of unity, at a specified temperature. The permeability of free space (a vacuum ) is a physical constant equal to approximately 1.257 x 10 -6 henry per meter.It is symbolized µ o.Permeability in general is symbolized µ, and is a constant of proportionality that exists between magnetic flux density and magnetic field strength in a given medium. Definition of Permeability 2. This constant is equal to approximately 1.257 x 10 -6 henry per meter (H/m) in free space (a vacuum). Magnetic Permeability Definition; Magnetic Permeability Formula; Types of Permeability Permeability of Stratified Soil Deposits. This helps in determining how much of magnetic flux can the material support which will pass through it. It is defined to have the exact value of 4π x 10-7 N/A 2 (newtons per ampere squared).
