where W is the index of sharpness of the particle size distribution, P90, P50 and P10 are the 90%, 50%, and 10% cumulative weight passing size, respectively. The smaller value of this index means the narrower particle size distribution, while the bigger value of this index means the wider particle size distribution. Simulation procedure
