  2. Submerged specific gravity - Wikipedia

    en.wikipedia.org/wiki/Submerged_specific_gravity

    Submerged specific gravity is a dimensionless measure of an object's buoyancy when immersed in a fluid.It can be expressed in terms of the equation = where stands for "submerged specific gravity", is the density of the object, and is the density of the fluid.

  3. Relative density - Wikipedia

    en.wikipedia.org/wiki/Relative_density

    A United States Navy Aviation boatswain's mate tests the specific gravity of JP-5 fuel. Relative density, also called specific gravity, [1] [2] is a dimensionless quantity defined as the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material.

  4. Specific weight - Wikipedia

    en.wikipedia.org/wiki/Specific_weight

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  5. Archimedes' principle - Wikipedia

    en.wikipedia.org/wiki/Archimedes'_principle

    In other words, the "buoyancy force" on a submerged body is directed in the opposite direction to gravity and is equal in magnitude to B = ρ f V g . {\displaystyle B=\rho _{f}Vg.\,} The net force on the object must be zero if it is to be a situation of fluid statics such that Archimedes principle is applicable, and is thus the sum of the ...

  6. Twaddell scale - Wikipedia

    en.wikipedia.org/wiki/Twaddell_scale

    On this scale, a specific gravity of 1.000 is reported as 0, and a specific gravity of 2.000 is reported as 200. [1] For example, concentrated sulfuric acid with a specific gravity of 1.8 has a Twaddell scale measurement of 160, reflecting the linear relationship between readings and specific gravity. The Twaddell scale is used exclusively for ...

    YouTube Music is a music streaming service developed by the American video platform YouTube, a subsidiary of Alphabet's Google. The service is designed with an interface that allows users to simultaneously explore music audios and music videos from YouTube-based genres, playlists and recommendations.

  9. Hydrostatic weighing - Wikipedia

    en.wikipedia.org/wiki/Hydrostatic_weighing

    The procedure, pioneered by Behnke, Feen and Welham as means to later quantify the relation between specific gravity and the fat content, [1] is based on Archimedes' principle, which states that: The buoyant force which water exerts on an immersed object is equal to the weight of water that the object displaces.
