Question

The design value of the velocity of flow in a flocculator is _______

(a) 0.2-0.8m/s

(b) 0.3-0.5m/s

(c) 0.6-0.8m/s

(d) 0.1-0.5m/s

The question was posed to me by my school teacher while I was bunking the class.

The doubt is from Flocculation and Clarification in chapter Sedimentation of Environmental Engineering

Answer 1

The correct choice is (a) 0.2-0.8m/s

For explanation: The normal value of the velocity of flow in a flocculator is 0.4m/s and its range is 0.2-0.8m/s.
