You are trying to remove 10.0 μm diameter particles in a water treatment plant, so you design a settling basin. The water is at 20 ̊C (giving a water density of 998.2 kg/m3, but really you can assume 1000 kg/m3 here), and the particle density is 1.2 g/mL. The plant treats 0.100 m3/s of water. It is proposed to use a 3.5 m deep, rectangular sedimentation tank with a length to width ration of 5:1. What is the minimum required width of the basin?
