1. A mechanical shaker was used to sieve a sample of spherical particle. The density and shape factor of the particles are found to be 2600 kg/m and 0.5, respectively. Based on the data given in the Table Q1, determine the following for this screen analysis. Table Q1: Mass distribution of crushed particle. Surface area of mesh per 500 screen Mass retained (g) opening (mm) 1000 10 562.5 15 250 35 62.5 20 2.5 20 (i) (ii) (iii) (iv) (v) Specific surface of mixture Mass mean diameter Number of particles distribution by fraction Total volume of particles in mixture Total surface of particles in mixture
