Determination of the true density of pulverized coal samples

The true density of a solid is calculated as the true unit volume of the solid exclusive of its pore space which is divided into the weight of the sample. The method is similar to that used to determine the density of refractory materials but the procedure is modified to yield precise density determinations of coal …

The specific gravity of coal is important during coal cleaning because many of the common mineral impurities in coal have much higher specific gravity (density) than coal. For example, the specific gravity of pyrite (fool's gold), a common impurity in coal, and the main source of sulfur in coal, is 4.9 to 5.2.

Flue Gas Density Calculator • FGKH

Flue Gas Density Calculator is based on Ideal Gas Law. The flue gas density of a flue gas can be measured using the ideal gas law. It has to be assumed that a real gas behaves as an ideal gas; this assumption is true when gas is at low pressure, so molecular interactions don't affect the system.

Energy density and the cost, weight, and size of onboard energy storage are important characteristics of fuels for transportation. Fuels that require large, heavy, or expensive storage can reduce the space available to convey people and freight, weigh down a vehicle (making it operate less efficiently), or make it too costly to operate, even after taking account of cheaper fuels.
