Calculate percent solids in a slurry from dry-solids mass and total slurry mass, find either mass from a solids %, or estimate it from densities.

Compare dry-solids mass with total slurry mass.

Mass of the solids after drying, with no water left in them.

Percent Solids In Slurry Formula

The following equation calculates Percent Solids In Slurry by mass. Total slurry mass includes both dry solids and liquid; use compatible mass units.

PSS = MS / MSL × 100
  • Where PSS is the percent solids in slurry (%)
  • MS is the mass of all solids in the slurry
  • MSL is the mass of the entire slurry

To calculate the percent solids in a slurry, divide the mass of the solids by the mass of the slurry, then multiply by 100.

What is Percent Solids In Slurry?

Definition:

Percent solids by mass is the dry-solids mass divided by total slurry mass, multiplied by 100. A slurry is a mixture of solid particles and liquid; its solids percentage by volume is a different basis.

How to Calculate Percent Solids In Slurry?

Example Problem:

The following example outlines the steps and information needed to calculate Percent Solids In Slurry.

First, determine the mass of the solids. In this example, the mass of the solids is found to be 400 grams.

Next, determine the mass of the total slurry. For this problem, the total slurry mass is measured to be 800 grams.

Finally, calculate the percent solids in slurry using the formula above:

%S = MS / MSL * 100

%S = 400 / 800 * 100

%S = 50%
