Slurry Solids Calculator
Slurry solids calculations split a slurry stream into its solids and liquid mass components. This calculator works on a mass basis only — it does not model density, viscosity, rheology, settling, or pipeline pressure drop. You supply mass flows and percent solids; the calculator returns the complementary values.

Formulas
Percent solids
% solids = (ṁ_solids / ṁ_slurry) × 100
Solids mass flow
ṁ_solids = ṁ_slurry × (% solids / 100)
Slurry mass flow
ṁ_slurry = ṁ_solids / (% solids / 100)
Liquid mass flow
ṁ_liquid = ṁ_slurry − ṁ_solids
Diagram
Worked example
A slurry stream flows at 100 t/h with 40% solids by mass. What are the solids and liquid mass flow rates?
- 01ṁ_solids = ṁ_slurry × (% solids / 100)
- 02ṁ_solids = 100 × (40 / 100) = 40 t/h
- 03ṁ_liquid = ṁ_slurry − ṁ_solids
- 04ṁ_liquid = 100 − 40 = 60 t/h
Result
Solids mass flow is 40 t/h. Liquid mass flow is 60 t/h.
FAQ
Does this calculate slurry rheology?
No. Rheology (yield stress, viscosity, flow behaviour) is not modelled. This calculator handles mass-basis solids splitting only.
Does this calculate slurry pipeline pressure drop?
No. Pipeline pressure drop requires pipe diameter, slurry rheology, velocity, and other parameters that are outside the scope of this calculator.
Does this calculate settling velocity?
No. Settling velocity requires particle size, density, and fluid properties that are not included.
Does this use particle size or viscosity?
No. This is a mass-balance calculator only. It does not use particle size, density, or viscosity.
