7.1: Surface Tension, Viscosity, and Capillary Action

WebDuring a flood, the water level always rises, so there is more cross-sectional area for the water to flow in; however, as long as a river remains confined to its channel, the velocity of the water flow also increases. Figure 13.15 … 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.
