There is a sedimentation tank that is used to remove suspended solid particles (diameter of 100 um an a particle density of 2,650 kg/m³) from an incoming wastewater stream. The incoming wastewater has a flow rate of 150 m /hr and the sedimentation tank has a basin surface area of 15 m2. Assume the operation temperature is 25 °C and assume that sedimentation is the only process by which suspended solid particle are removed from the sedimentation tank. For water at 25°C: p = 999.7 kg/m3 and u = 1.307 x 10-3 N s/m2 g(Pp-Pr) D Vs 3= 18 μ a) What is the settling velocity (vs) of the suspended solids in this sedimentation tank in the unit of m/s?
