When the axis of rotation, because of the imbalance in the quality of centrifugal force between the utility, will the initiation of buckling deformation.

The water current will do curve movement after getting into the bend channel, under the together function of centrifugal inertial force and gravity, and the fluid state becomes exceptionally complex.

Of all the additional forces, only the tangential force effects on the flow. The effect of centrifugal and Coriolis forces on the flow is counteracted.
