hindered settling

Problems 6.9

Question 1.6


Height of the settling interface against time graph. Batch settling curve
As settling rate is independent of vessel diameter one design is to construct a vessel of height given in Part 4 (i.e. 12.6 cm). The total vessel volume would need to be sufficient to accommodate the volumes given in Part 2 (i.e. 1350 m3 at the start of the third day's sedimentation).

This would make the vessel area (m2):

a) 4825
b) 1070
c) 48250
d) 10700
