Enter the concentration of solids by weight (%), the density of the solids (kg/m^3), and the density of the liquid without solids (kg/m^3) into the Slurry Density Calculator. The calculator will evaluate and display the Slurry Density.

## Slurry Density Formula

The following formula is used to calculate the Slurry Density.

SD = 100 / (C / ds + (100-C) / dl )

• Where SD is the Slurry Density (kg/m^3)
• C is the concentration of solids by weight (%)
• ds is the density of the solids (kg/m^3)
• dl is the density of the liquid without solids (kg/m^3)

## How to Calculate Slurry Density?

The following example problems outline how to calculate Slurry Density.

Example Problem #1

1. First, determine the concentration of solids by weight (%).
1. The concentration of solids by weight (%) is given as 50.
2. Next, determine the density of the solids (kg/m^3).
1. The density of the solids (kg/m^3) is calculated as: 40.
3. Next, determine the density of the liquid without solids (kg/m^3).
1. The density of the liquid without solids (kg/m^3) is found to be: 30.
4. Finally, calculate the Slurry Density using the formula above:

SD = 100 / (C / ds + (100-C) / dl )

Inserting the values from above yields:

SD = 100/ (50 / 40 + (100-50) / 30 )  = 34.285 (kg/m^3)

Example Problem #2

The variables needed for this problem are provided below:

concentration of solids by weight (%) = 60

density of the solids (kg/m^3) = 70

density of the liquid without solids (kg/m^3) = 80

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.

SD = 100 / (C / ds + (100-C) / dl )  = (kg/m^3)
