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.

Relative density is defined as the ratio of density of the substance to the standarnd which is either air for gases and water for liquids or solids.

2019年3月18日 · Relative density (RD) is the ratio of the density of a substance to the density of water. It is also known as specific gravity (SG). Because it is a ratio, relative density or specific …

2023年7月6日 · Relative density, also known as specific gravity, is the ratio of the density of a substance to the density of a reference substance (usually water) at a specific temperature. …

Density and relative density are both important concepts in the study of materials and their properties. While density measures the mass per unit volume of a substance, relative density …

2024年5月21日 · 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 is …

The relative density of solids or liquids is the ratio between the mass of a volume of a substance to be examined, determined at 20°C, and the mass of the same volume of water, determined …

Roughly speaking, the relative density is the amount of fluid (as opposed to pore) contained in a typical unit cell. The most important feature of this graph is that, at early times, the relative …
