Webestimate of size because passage through the sieve aperture is frequently more dependent on maximum width and thicknessthanonlength. This method is intended for estimation of the total particle-size distribution of a single material. It is not intended for determination of the proportion of particles passing or retained on 1 or 2 sieves. WebMeasurement of particle size: • The slide is focus in low power (10x) the presence of individual particle is absorb (if aggregation or lumps are present the sample should be mounted again) • The size of the each particles measure is terms of eye piece division • A total 300 particles should be considered for size distribution analysis.

The particle size determined is a hydrodynamic diameter. The Stokes-Einstein equation describes the relationship between particle size, diffusion rate, temperature and viscosity:
WebFeb 15, 2024 · Sieving method of particle size determination. Particles with a size range of 50 to 1500μm are measured by this method. The size of particles is expressed as d seive which is the diameter of the sphere that passes through the sieve aperture. This is a rough and fast method and one can obtain the weight distribution of particle sizes.
