  2. Area density - Wikipedia

    en.wikipedia.org/wiki/Area_density

    The area density (also known as areal density, surface density, superficial density, areic density, mass thickness, column density, or density thickness) of a two-dimensional object is calculated as the mass per unit area. The SI derived unit is the "kilogram per square metre" (kg·m −2).

  3. Fiber volume ratio - Wikipedia

    en.wikipedia.org/wiki/Fiber_volume_ratio

    The density is determined by weighing the sample in air and then in a liquid of known density. Application of Archimedes’ principle leads to the following expression for the measured density of the sample in terms of measured weight, where subscripts “a” and “L” refer to water and liquid, respectively: [ 5 ]

  4. Specific surface area - Wikipedia

    en.wikipedia.org/wiki/Specific_surface_area

    Specific surface area (SSA) is a property of solids defined as the total surface area (SA) of a material per unit mass, [1] (with units of m 2 /kg or m 2 /g). Alternatively, it may be defined as SA per solid or bulk volume [ 2 ] [ 3 ] (units of m 2 /m 3 or m −1 ).

  6. Floor area ratio - Wikipedia

    en.wikipedia.org/wiki/Floor_area_ratio

    In the United States and Canada, floor space ratio (FSR) and floor area ratio (FAR) are both used. [10] Use ratios are used as a measure of the density of the site being developed. High FAR indicates a dense construction. The ratio is generated by dividing the building area by the parcel area, using the same units.

  8. Thin-film equation - Wikipedia

    en.wikipedia.org/wiki/Thin-film_equation

    The basic form of a 2-dimensional thin film equation is [3] [4] [5] = where the fluid flux is = [(+ ^) + ^] +, and μ is the viscosity (or dynamic viscosity) of the liquid, h(x,y,t) is film thickness, γ is the interfacial tension between the liquid and the gas phase above it, is the liquid density and the surface shear.
