Question

What is a cumulative undersize particle distribution?

Short answer

Cumulative undersize particle distribution deals with a value of diameters of particles having a less or equal diameter from the value as a function of diameter.

Step-by-step solution

Concept Introduction

Particles can be most usually represented as spheres with a volume equal to that of the sphere. Many graphs for particle distribution may be determined based on volume and other characteristics.

Explanation

• The parameters to measures particle size distribution are the different sized particles present in a sample and the distribution of intensity of scattered light.
• The relationship between response function and detector output can also be considered as a parameter in order to calculate particle size distribution.
• In the case of Cumulative particle size distribution, a value is given for each particle diameter.
• This value is the representation of the percentage of particles that have a less or equal diameter from the value as a function of diameter.
• The graph shown below represents a typical cumulative undersize particle distribution.

Final answer

The cumulative particle size distribution is the distribution of diameter values of particles with a smaller or equal diameter than the value given as a component of diameter measurement.
