Relative density or density index is the ratio of the difference between the void ratios of a cohesionless soil in its loosest state and existing natural state to the difference between its void ratio in the loosest and densest states. Where, e max = void ratio of coarse grained soil ( cohesionless) in its loosest state.

- Difference Between Density and Specific Gravity

Also, density is expressed in units (weight relative to size) while specific gravity is a pure number or dimensionless. What Is Density? Density is a property of matter and can be defined as the ratio of mass to a unit volume of matter.

- Difference Between Density and Bulk Density ...

Jul 30, 2011 · The terms relative density and specific gravity are used to compare the densities of two given substances. They are dimensionless quantities, displaying the ratio between two densities. In some cases, the density is also defined as the weight of a given volume divided by the volume. It is usually known as apparent density. Bulk Density

- Specific Gravity Of General Materials Table - CSGNetwork

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that a sample of ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.

For example, the density of a one-inch cube of iron is much greater than the density of a one-inch cube of cotton. In most cases, denser objects are also heavier. 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.

- What is the density of coal - Answers

The density of coal is 1,330kg/m^3 whereas for diamond it is 3,520,000,000 kg/m^3. When diamond is divided by coal, we learn that diamond is 2,646,616.5414 times more dense than coal.

- What Is the Bulk Density of Coal? | Reference

The bulk density of coal depends on the specific type of coal. It can range from 40 to 58 pounds per cubic feet, or 641 to 929 kilograms per cubic meter. The three types of coal are anthracite coal, bituminous coal and lignite coal. Anthracite coal has a bulk density of 50 to 58 pounds per cubic feet, or 800 to 929 kilograms per cubic meter.

- The Density of Common Rocks and Minerals - ThoughtCo

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/cm3. Therefore, these numbers translate directly to g/cm3, or tonnes per cubic meter (t/m3).

- GP Coal Slurry - User page server for CoE

Specific gravity of coal = G = 1.3(i.e. density of coal = 1.3×density of water) Installed cost of pipe ($/ft) including right-of-way: 52 CD D1 =+10.03 where D is the inside diameter (inches) Installed cost of pumping stations: Chp p =$250/ of pump capacity Installed cost of system for injecting coal at beginning of line and separating at end of line

- Studies on the Variation in Coal Properties of Low ...

The relative abundance of coal in India compared to other fossil fuels makes it a natural choice as the primary source of fuel, be it for steel making, power generation or for other uses. Total reserves of coal in the country are estimated to the order of 267 Billion Tons. Coking coal, which is merely 14% of the total deposits, is available mainly in Eastern part of India.
