2. A suspension of particles with a particle density of 2796 kg/m³ is settling in water with a temperature of 20 °C. For each 100 kg of particles, the following distribution of particle sizes applies: Group No. Mass of particles of each size, kg Particle size, mm 1 50 0.085 2 20 0.070 3 20 0.060 4 10 0.050 Calculate the percent removal of particle mass if the settling tank was designed to remove 100% of the particles with size = 0.085 mm. Assume spherical particles.
