Abstract: A new formula for evaluating the mean velocity gradient G of high turbidity water flow in pipes is set up based on the mixing length theory of turbulent flows, which is proved valid for the hyper-concentrated turbulent flow in pipes. A test study is conducted to investigate the flocculation of high turbidity water flow in pipes. It is found that the optimum value of mixing reaction extent GT is 60～120.
