3) (15 points) You are asked to design sedimentation basins for a new drinking water treatment plant with a flow of 7,500 m³/d. Given that the diameter of the particles to be removed is 0.010 mm, the particle density is 1,397 kg/m³, and the water temperature is 20°C, determine: a) The terminal settling velocity. b) Would particles of this size and density be completely removed in a rectangular settling basin with a width of 10 m, a depth of 3 m, and a length of 20 m?
