The investigations presented here are focused on the effect of sieving in a set, the statistical variation in the sieving process, and calibration of a sieve set. The sieving procedure used by our group is described in the appendix. A general treatment of sieving analysis can be found in Ingram (1971), Allen (1981), and Kaye (1981).

Sieving is commonly employed in various daily life activities. It is the most popular type of separation process due to its convenience. Separating rice from the water after boiling it using a kitchen sieve is a recurrent example of the process. Sieving can be utilized here since rice is in a solid state and the boiled water is in its liquid state.
