Webflow behavior depends on the history of what forces were applied to the fluid. Such fluids include thixotropic (shear-thinning over time) and rheopectic (shear-thickening over time) types. Viscoelastic fluids exhibit elastic or solid-like behavior when forces are first applied, and then transition to viscous flow under continuing force. desk and chair set for teenagerswhere: K is the flow consistency index ( SI units Pa s n ), ∂ u / ∂ y is the shear rate or the velocity gradient perpendicular to the plane of shear (SI unit s −1 ), and n is the flow behavior index ( dimensionless ).
