The data are presented on a semilog plot of percent finer vs. particle diameters and may be combined with the data from a sieve analysis of the material retained (+) on the No.200 sieve.
soil for sand content (using a 53 µm sieve, No. 270) after the last hydrometer reading has been taken. Then a 7 or 24 hour hydrometer reading can be used for clay content, the mass of soil on a 53 µm sieve is used for the sand content, and silt is determined by difference. In this case a 40 second hydrometer reading would be unnecessary.Sieve analysis which is used for particle sizes larger than 0.075 mm in diameter and; Hydrometer analysis which is used for particle sizes smaller than 0.075 mm in diameter; Sieve analysis is a method that is used to determine the grain size distribution of soils that are greater than 0.075 mm in diameter.This hydrometer analysis laboratory was conducted in order to quantify the relative distribution of grain sized for a fine-grained soil sample.
