Exercise n.7 Determine the percent fraction of particles removed in a sedimentation basin considering a wastewater (temperature T=20C ) with the particle size distribution shown in the following table and subjected to sedimentation type 1 under ideal conditions. Assume the following data: - average density of the solid particles, p=3000(kg/m3) - density of the fluid at T=20C,pf=998.2(kg/m3) - dynamic viscosity of the fluid at T=20C,f=1.002103(Ns/m2) - acceleration due to gravity, g=9.81(m/s2) - overflow rate, v0=3800(m3/m2d)
