Equivalent Particle Size
Definition
Size inferred under a specified measurement model rather than every physical dimension. A method can express particle size as an equivalent diameter under its model, such as a response corresponding to an idealised shape.
- Context
- Particle measurement
For example, an irregular flake can have one reported equivalent diameter while its length and thickness differ substantially from that value.
That value need not equal every physical dimension of an irregular particle. Compare measurement bases before treating two size distributions as equivalent.
