A rectangular horizontal-flow sedimentation basin in a conventional water treatment plant has been designed to treat a flow of 50,000 m3 /day. It has a length = 80 m, width = 20 m, and depth = 3.6 m. For this problem, assume temperature = 20 °C (density of water = 103 kg/m3 and viscosity = 10-3 kg/m·s) and laminar flow. a. What is the hydraulic detention time? Does this meet the typical criteria for this type of sedimentation basin? b....
