Sedimentation

Jan 31, 2026

Sedimentation is the process by which solid particles suspended in a liquid settle to the bottom of a container due to gravity.

The rate of sedimentation depends on:

  • Particle size (larger particles settle faster)
  • Density difference between particle and liquid
  • Viscosity of the liquid
  • Gravitational or centrifugal force

Common examples: fruit pulp settling in juice, sand settling in water.
