The setting velocity of a particle is 0.002 m/s and the overflow rate of a settling tank is 0.008 m/s.
(a) what percent of the particles does the settling tank capture?
(b) If the particles are flocculated so that thie rsettling rate is 0.05 m/s, what fraction of the particles is captured?
(c) If the particles are not charged, and another settling tank is constructed to run in parallel with the original settling tank, will all of the particles be captured?
