\huge\color{red}{Solution:}

✔✔The uniformity coefficient Cu is defined as the ratio of D60 by D10. So when Cu is greater than 4 to 6, it is understood as a well graded soil and when the Cu is less than 4, they are considered to be poorly graded or uniformly graded. Uniformly graded in the sense, the soils have got identical size of the particles.

✔✔The mechanical or sieve analysis is performed to determine the distribution of coarser, larger sized particles, and hydrometer method used finer particles jul 30, 2013 sol'n; Cu d60 d10 0. 75 well graded sand, cu 6 and cc (1 3), otherwise, poorly graded.
