sieve analysis has resulted in the following particle size distribution: (a) Provide a table of mass fraction of the distribution. (b) Calculate the mean particle size by mass of the

distribution. (c) Estimate the median particle size by mass of the distribution. (d) Calculate the specific surface area per unit volume of the distribution using the tabulated data given above. (e) Calculate the Sauter mean diameter of the distribution. (f) Write down four different methods for particle size measurements. Describe the method that is commonly used in modern industry for microparticles.
