A rapid mixing basin is to be designed for a drinking watercoagulation plant with a 5 MGD flow. The geometry of the basin issquare with a depth equal to 1.5 times the width. The velocitygradient 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 abaffled tank given that the impeller diameter is 50% of the basinwidth
