Websistency index" and "flow-behavior index." These are the coeffi-cients of a simple power-law equation. A test fluid with K= 4400 cp and n=0.2 was used to evaluate the pressure drop of the 1" and 3" meters at the conditions outlined above. This is a fluid that at no flow has a viscosity of 4400 cp; at higher rates the viscosity will drop to as ... 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.
