Slurry - Density

Calculating density of slurries

Slurry is a mixture of solids and liquid. The density of a slurry can be calculated as

ρm = 100 / [cw / ρs  + [100 - cw] / ρl]         (1)

where

ρm = density of slurry (lb/ft3, kg/m3)

c= concentration of solids by weight in the slurry (%)

ρs =  density of the solids (lb/ft3, kg/m3)

ρl =  density of liquid without solids (lb/ft3, kg/m3)

The slurry concentration by weight can be measured by evaporating a known weight of slurry and measuring the weight of dried solids.

Example - Calculating Slurry Density

The density of a slurry where

  • the density of solids is 2500 kg/m3
  • the density of liquid is 1000 kg/m3
  • the concentration of solids is 30%

can be calculated as

 ρm = 100 / [(30 %) / (2500 kg/m3) + [(100 %) - (30 %)] / (1000 kg/m3)]

    = 1220 kg/m3
