Coal Density - an overview | ScienceDirect Topics

3.3.1 Moist Specific Gravity, Raw Coal Density. Moist specific gravity refers to the specific gravity of raw coal and is determined on a block of bed-moist coal (300-500 g) by weighing the block in air and then in water, i.e. it equals Wa/(Wa-Ww) where Wa and Ww are the weights in air and water respectively.
