How does cohesion influence flow

WebFlowability is often described on the basis of the flow function (Figure 1) [1] derived from shear testing. The flow function is a graph relating a major principal stress (σ 1) to the unconfined yield strength (f c) that it produces in a powder specimen. This graph basically describes cohesive strength as a function of compaction pressure. WebChanges in water flow patterns can be caused by earthquakes, previous slope failures that dam up streams, or human structures that interfere with runoff (e.g., buildings, roads, or …
