WebEveryday Newtonian fluids include examples such as water, dilute colloidal dispersions, and simple hydrocarbons. Non-Newtonian fluids are fluids that have a non-linear relationship, i.e. the viscosity varies as function of the applied shear stress or shear rate. Viscosity is also temperature and pressure dependent. WebNewtonian fluids, such as water or oil, are characterized by a viscosity (i.e. the ratio between shear stress and shear rate) that is independent of shear rate.These fluids display a linear relation between shear stress and shear rate. The only parameter needed to describe the model is the slope of the shear stress–shear rate relationship (Figure 7.4).
