Overview

When the sedimentation principle is used for granulometric analysis, it is using the fact that particles of different size have different velocities in a fluid at rest. Therefore, the temporal and spatial changes of concentration in a sedimenting system provide substantial information on the quantitative distribution of particle sizes characterized by the speed of their motion. The measurement of such distributions is called sedimentation analysis; it requires the theoretical understanding and experimental handling of the following two phenomena:
  1. 1.

    Connection between sedimentation velocity and particle size as a function of the material properties of the system and the other conditions in the sedimentation vessel (Chapter 3).

     
  2. 2.

    Connection between the concentration distribution of the solid observed after time t and its size distribution. This requires methods both indicating concentration changes and allowing us to calculate the distribution from the measured data.
