The specific gravity is directly proportional to the plasticity index of the refuse. As the plasticity index increases, the specific gravity also increases. WebJul 1, 2024 · The specific gravity of coal is the ratio of the density of coal to that of a reference substance (Usually water). This information can be used to tell whether coal will float (or sink) if dropped in water (Buoyancy). Formula SG = ρcoal / ρwater Note: Both densities need to be in the same unit as they will cancel each other and produce SG. optica foundation
