With steps Please!! Thanks e results of a sieve test on a sample of particulate material o mass 236g are given below, in addition to the results of a sedimentation test carried out on a representative sub-sample of the fine material (<63um). The mass of the sub-sample was 12g, the volume of the pipette was 10ml, and the overall volume of the suspension was 500ml. Plot the particle size distribution curve and calculate the uniformity coefficient and coefficient of curvature...
