Chapter 34, Problem 34.1QAP

Interpretation Introduction

Interpretation:

Normal particle size distribution and Cumulative particle size distribution are to be described.

Concept introduction:

Most commonly particles in the form of spheres and have an equivalent volume with the sphere. Based on volume and other parameters many graphs can be determined for particle distribution

Answer to Problem 34.1QAP

Diameter and volumes etc. are taken as parameter in case of normal particle size distribution but Cumulative particle size distribution is the representation of fraction of particle versus size of particle.

Explanation of Solution

Generally,particles are represented as spheres and have an equivalent volume with the sphere. In order to describe particle size distributions D values are commonly used.

It is assumed that the density is constant; with a change in mass it may be interchangeable. Based on volume and other parameters many graphs can be determined for particle distribution. Parameters such as diameter and volumes which have particular values are taken in case of normal particle size distribution. Cumulative particle size distribution plot is plotted between fraction of particle and the size of particle.

Conclusion

Normal particle size distribution but Cumulative particle size distribution differs from each other in the prospectus of parameters. Normal particle size distribution takes Diameter and volumes as parameters and Cumulative particle size distribution

Case of Cumulative particle size distribution is taken as parameters.
