Physical Properties of a Slurry: Since the slurry consists of solid particles suspended in a liquid, the properties of a slurry mixture will depend upon those of the constituents. The density of slurry can be calculated from the following equation: ρ m = 100 / (C w /ρ s) + [(100 - C w) / ρ L] where: ρ m =density of slurry mixture, kg/m 3
