Webb29 juni 2024 · This is an example of the enigma that is sludge rheology. Rheology concerns the relationship between shear stress and shear rate. The shear stress is the force applied parallel to and at the liquid interface – as with, say, a skimmer. The shear rate γ is defined by how fast this force is applied.
