Question

A rapid mixing basin is to be designed for a drinking water coagulation plant with a 5 MGD flow. The geometry of the basin is square with a depth equal to 1.5 times the width. The velocity gradient is 950 s·1 with a detention time of 25 s.

Calculate

a) The basin dimensions using minimum increments of 1"

b) The input hp required

c) The impeller speed with six flat blades employed and a baffled tank given that the impeller diameter is 50% of the basin width
