1.	Analysis of very small size grains of soil can also be possible by using sieves.(a) True(b) FalseI got this question in an online interview.I'd like to ask this question from Grain Size and Shape topic in section Molding and Core Sands of Casting-Forming-Welding I
Answer» Right option is (B) False The best I can explain: Analysis of very small size GRAINS of soil cannot be possible by using SIEVES, because of very small size of SIEVE openings, it is very difficult to get PASS the grains. Then for the analysis of small size grains, hydrometer analysis is done which is based on stoke’s law that states that the larger the grain size, the larger it’s settling speed in a fluid.
