Question

The effective size of a particles of soil is denoted by

Answer 1

Concept Introduction:-

Effective Size are the dimension that directly reflects the proportion of grains on the size of the grain diagram that are $10$ percent in weight.

Explanation:-

A question has been provided to us

We need to find the solution to the question

The diameter in the particle-size distribution curve corresponding to $10 \%$ finer is defined as the effective size or $D_{10}$

To obtain the grading characteristics, three points are located on the grading curve.

The effective particle size of soil can be related to other soil properties such as the liquid limit, plasticity index, the unconfined compressive strength and the standard penetration test number of blows $( \mathrm{N})$.

Final Answer:-

The correct answer is The diameter in the particle-size distribution curve corresponding to $10 \%$ finer is defined as the effective size or $D_{10}$.
