Coal has relatively low density or specific gravity (1.2 to 1.5) compared to other rocks such as shale (2.4 to 2.8) or minerals such as pyrite (4.9 to 5.2). Hence, float-sink analyses are usually run in liquids with densities between 1.3 and 2.0. ### ASTM-D3588 | Standard Practice for Calculating Heat Value, Compressibility Factor, and Relative Density

Scope 1.1 This practice covers procedures for calculating from compositional analyses, the following properties of natural gas mixtures: heating value, relative density and compressibility factor at base conditions (14.696 psia and 60 F). It is applicable to all common ### ISO 23499: (en), Coal ? Determination of bulk density for

The bulk density of coal is influenced by its physical characteristics, such as relative density, shape and size distribution of the coal particles, on the coal moisture content as well as on the dimensions of the measuring container. ### What Is the Formula for Relative Density?

Mar 31, · The relative density formula calculates the density of the substance in question in comparison with a second substance, called the reference substance. Specific gravity is similar to relative density, although it is typically used in measurements where the reference substance is water. ### The Density of Common Rocks and Minerals

Jan 23, · The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water. This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3. Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3). ### ASTM Standard - Volume 05.06 Gaseous Fuels, Coal and Coke
