• ## Relative density - Wikipedia

en.wikipedia.org/wiki/Relative_density Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference.

www.dictionary.com/browse/relative-density noun. the ratio of the density of a substance to the density of a standard substance under specified conditions. For liquids and solids the standard is usually water at 4°C or some other specified temperature. For gases the standard is often air or hydrogen at the same temperature and pressure as the substanceSymbol: d See also specific gravity, vapour density.

• ## Relative Density Definition in Chemistry - ThoughtCo

www.thoughtco.com/definition-of-relative-density-605608 Relative density (RD) is the ratio of the densityof a substance to the density of water. It is also known as specific gravity(SG). Because it is a ratio, relative density or specific gravity is a unitless value. If its value is less than 1, thenthe substance is less dense than water and would float.

www.differencebetween.net/.../difference-between-density-and-relative-density Density is the ratio between the mass and the volume of a body. Relative density, on the other hand, is the ratio between the density of an object (substance) and the density of some other reference object (substance) at some given temperature. Density is measured in, while relative density is dimensionless.

www.differencebetween.com/difference-between-relative-density-and-vs-density Relative density is density of an object in terms of the density of another reference object. Relative density is defined as the ratio between density and density of the reference object. Hence, it is a dimensionless quantity, and has no measuring unit.
• ## How to Determine the Relative Density of Soils

www.soilmanagementindia.com/soil/determination-of-relative-density/.../13328 Thus relative density (D r ), also called density index (I d ), is defined by –. D r = [ (e max – e)/ (e max – e min )] x 100 … (4.80) where e max is the maximum void ratio of soil corresponding to the loosest state, e is the in-situ void ratio, and e min is the minimum void ratio of soil corresponding to the densest state.
