Appendix C: Definitions and Conversions for Concentration

The most frequently used expressions for suspension concentration are defined according to equations (C.1) (C.7):








where M l is the mass of liquid, M s the mass of solid, ? l the volume of liquid and ? l the volume of solid. If ? l is the liquid density and ? s the solids density, several conversion formulae between these expressions can be established.

Mass Fraction (s) ? Volume Fraction (V s) Conversions



Mass, Volume Fraction (s; V s) ? Mass of Solid/Volume of Liquid (C l) Conversions





Mass, Volume Fraction (s; V s) ? Mass of Solid/Volume of Suspension (C s) Conversions





Mass of Solid/Volume of Liquid (C l) ? Mass of Solid/Volume of Suspension (C s) Conversions



Mass, Volume Fraction and Mass of Solid/Volume of Liquid or Suspension (s; V s; C l; C s) Mass Ratio (M R) Conversions









Mass, Volume Fraction and Mass of Solid per Volume of Liquid or Suspension (s; V s; C l; C s) ? Volume Ratio (V R) Conversions









Note: The expressions (C.1) (C.35) can also be applied to filter cakes by replacing values for suspension with values for cake . In such instances, V s is equivalent to C av.
