  2. SEEP2D - Wikipedia

    en.wikipedia.org/wiki/SEEP2D

    SEEP2D is a 2D seepage analysis program written by Dr. Fred Tracy of the United States Army Corps of Engineers. The program is used to analyze water seepage, typically through dams and levees or under sheet piles. "The model is internationally known in the engineering community as a model for complicated seepage analysis of dams and levees."

  3. Permeability (materials science) - Wikipedia

    en.wikipedia.org/wiki/Permeability_(Materials...

    The SI unit for permeability is the square metre (m 2).A practical unit for permeability is the darcy (d), or more commonly the millidarcy (md) (1 d ≈ 10 −12 m 2). The name honors the French Engineer Henry Darcy who first described the flow of water through sand filters for potable water supply.

  4. Moisture vapor transmission rate - Wikipedia

    An MVTR result without specifying these conditions is almost meaningless. Certainly no two results should be compared unless the conditions are known. For example, the effect of temperature on the permeability can be as high as 10% per °C, making it possible that MVTR results achieved at 23°C and 37°C can differ by a factor 4.

  5. Permeability - Wikipedia

    en.wikipedia.org/wiki/Permeability

    Permeability (earth sciences), a measure of the ability of a material (such as rocks) to transmit fluids Relative permeability, in multiphase flow in porous media; Permeability (foundry sand), a test of the venting characteristics of a rammed foundry sand; Hydraulic conductivity, the permeability of soil for water

  6. Permeation - Wikipedia

    en.wikipedia.org/wiki/Permeation

    Permeation can occur through most materials including metals, ceramics and polymers. However, the permeability of metals is much lower than that of ceramics and polymers due to their crystal structure and porosity. Permeation is something that must be considered carefully in many polymer applications, due to their high permeability.

  7. Fluid flow through porous media - Wikipedia

    en.wikipedia.org/wiki/Fluid_flow_through_porous...

    The movement of a fluid through porous media is described by the combination of Darcy's law with the principle of conservation of mass in order to express the capillary force or fluid velocity as a function of various other parameters including the effective pore radius, liquid viscosity or permeability. [3]

  8. Air permeability specific surface - Wikipedia

    en.wikipedia.org/wiki/Air_permeability_specific...

    In particular, air permeability is almost universally used in the cement industry as a gauge of product fineness which is directly related to such properties as speed of setting and rate of strength development. Other fields where air permeability has been used to determine specific surface area include: Paint and pigments; Pharmaceuticals

  9. List of audio conversion software - Wikipedia

    en.wikipedia.org/wiki/List_of_audio_conversion...

    An audio conversion app (also known as an audio converter) transcodes one audio file format into another; for example, from FLAC into MP3. It may allow selection of encoding parameters for each of the output file to optimize its quality and size.
