A mixture of particulate materials (A) and (B) having a size range of 6.10106m to 3.50105m is to be separated by hydraulic classification using free settling conditions in water at 293.2K. PA=6750kg/m3W=998kg/m3PB=1850kg/m3W=1.005103kg/(m.s) A-Calculate the size range of the various fractions obtained in settling. B- The solid mixture obtained from the above separation stage is to be further separated by hydraulic classification using free settling conditions in a mixture of a miscible liquid (L) in water at 293.2K. (30%w/w miscible liquid). The density and viscosity of the miscible liquid at the mentioned conditions are 950kg/m3 and 1.005103kg/(m.s) respectively. Calculate the new size range of the various fractions obtained in settling. C - Find out which is more effective to the separation process, change in density or viscosity of the fluid
