Abstract
The modes of conventional analysis of ‘column settling data’ differ with nature of suspension. The methods are inadequate. The inadequacies are pointed out. A single method without any consideration to the nature of suspension and without any assumption is presented. The applications are illustrated with actual analysis of laboratory settling data.
