Slurry Density

Calculate slurry density

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

ρ_m = 100 / (c_w / ρ_s  + (100 - c_w) / ρ_l) (1)

where

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

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

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

ρ_l =  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

 ρ_m = 100 / (30 / 2500  + (100 - 30) / 1000)

    = 1220 kg/m³
