A new water treatment plant is going to be constructed in Jacksonville to replace the existing plant. The average annual water temperature is 19 oC. The following design assumptions for a flocculation tank have been made: Number of tanks = 1 Detention time = 40 min Velocity gradient = 25 s−1 Impeller type: radial, 3 flat blades, Np = 0.33 Impeller diameter = 1.1 m Rotational speed = 30 rpm What is the design flow rate in m3/d?

A new water treatment plant is going to be constructed in Jacksonville to replace
the existing plant. The average annual water temperature is 19 oC. The following design
assumptions for a flocculation tank have been made:
Number of tanks = 1
Detention time = 40 min
Velocity gradient = 25 s−1
Impeller type: radial, 3 flat blades, Np = 0.33
Impeller diameter = 1.1 m
Rotational speed = 30 rpm
What is the design flow rate in m3/d?
