Relating Hydraulic Conductivity to Particle Size Using

It is widely known that the packing characteristics of a granular material are governed by the size of the particles. It has been accepted for many years for example that the porosity (or density) of a granular soil depends on the distribution and range of particle sizes (e.g., Burmister 1938).The packing of a granular material strongly influences the macroscopic engineering properties; for ...

Understanding and Interpreting Particle Size

All particle size analysis instruments provide the ability to measure and report the particle size distribution of the sample. There are very few applications where a single value is appropriate and representative. The modern particle scientist often chooses to describe the entire size distribution as opposed to just a single point on it.

Cluster Size Distribution in a System of Randomly

The distribution function of particles over clusters is proposed for a system of identical intersecting spheres, the centers of which are uniformly distributed in space. Consideration is based on the concept of the rank number of clusters, where the rank is assigned to clusters according to the cluster sizes. The distribution function does not depend on boundary conditions and is valid for ...
