What is relative density
{\rm {grams}}/ {\rm {c}} { {\rm {m}}^3}.\)The symbol denoting relative density is sg.The relative density of rubbing oil is.79gram/cm3, the density of water is 1gram/cm3.Relative density is also known as specific gravity.It tells you, how dense a material is compared to another.
Relative density is the ratio between the density of a measuring substance and the density of some other reference substance at a given temperature (typically water).Relative density is a ratio so it has no unit.Relative density is the comparison of the density of one material to the density of a particular standard, such as water, at a given temperature or pressure.Relative density of a substance is defined as the ratio of its density to the density of water at 4°c.This quantity was formerly called specific gravity.
The term relative density is dimensionless.The density of a substance gives an idea of purity.Because it is a ratio, relative density or specific gravity is a unitless value.When the reference substance is water in case of solids or liquids and hydrogen in case of gases, the relative density is referred to as specific gravity.It is the degree of denseness or looseness of natural deposits of coarse grained soils.
A substance can be compared to numerous reference substances, thus having different relative densities.Relative density of a given material is defined as density of the given material / density of the reference material.
