Uniformity coefficient is a measure of particle size range.
Explanation:
Particle size distribution is an important characteristic of soils and other granular materials, as it affects their physical and engineering properties. Particle size range can be quantified by various parameters, such as effective size, coefficient of curvature, and uniformity coefficient.
- Effective size: It is the particle size for which 10% of the soil particles are finer, by weight.
- Coefficient of curvature: It indicates the degree of curvature of the particle size distribution curve. A value of 1 indicates a perfect straight line, while higher values indicate a more curved distribution.
- Uniformity coefficient: It is defined as the ratio of the particle size corresponding to 60% finer, by weight, to the particle size corresponding to 10% finer, by weight. It is a measure of the range of particle sizes in a soil sample.
Therefore, option B is correct, as uniformity coefficient is specifically a measure of particle size range.
