noun

• A quantity related to the size of a microscopic particle, equal to the terminal outward velocity of the particle when centrifuged in a fluid medium divided by the centrifugal force acting on it, expressed in units of time.

  ‘This limitation arises from the complex relationship between the shape of a particle and its sedimentation coefficient.’
