WebA plot of stress versus shear rate yields a straight line with the slope equal to the viscosity. A viscosity versus shear rate plot yields a horizontal line as the viscosity is independent of shear rate. All gases obey Newton’s law and are Newtonian fluids. Mineral oils and blends of mineral oils are also generally Newtonian in flow behavior.
