What is the density of coal? – Restaurantnorman

2021-5-11  What is the relative density of coal? Coal density should be determined from average specific gravity of various coal rank as in 1.29 for lignite coal, 1.30 for subbituminous coal, 1.32 for bituminous coal, and 1.47 for anthracite and semianthracite coal. What is the density of coal in kg m3? 1 506 kilogram per cubic meter

Coal Density - an overview ScienceDirect Topics

Coal density is among the important parameters for reservoir engineering purposes and is inserted as an input property in simulation studies. Coal density is typically less than that of conventional reservoirs and differs from seam to seam based on the given coal rank and purity [2].The bulk density of a coal consists of the matrix and the void space, with the latter being expectedly filled ...
