Webblence, and when in a round pipe the ratio reaches 2,300 (that is, 2,300;1), the flow becomes turbulent. The turbulence in turn increases the capacity of the pipe to carry solids. This last point is easily rec ognized in the flow of a river: at its head high in the mountains the river flows fastest and carries the coarsest solid ma WebbThe Pipe Flow interface allows you to simulate non-Newtonian fluids flowing in pipes. This example models a coal slurry being transported in a pipe system where the pipe diameter changes in different sections. The slurry behaves as a non-Newtonian fluid described by the power law model.
