Asettling tank is to precipitate (m) high. the density of the solid is 2500 kg/m3; the horizontal velocity of the input suspension is 0,015 (m/s). supposing the viscosity of the suspension is the viscosity of water at the ambient temperature, the settling process is working at stokes-laminar hydraulic mode. dispersed solid particles in water. the tank is 40 (m) long and 8 est particles that settle in the tank? ) b) if the smallest particle is 30 (um) in diameter, what is the length of the tank ?
