WebShear rate is the rate at which a progressive shearing deformation is applied to some material. The shear rate for a fluid flowing between two parallel plates, one moving at a constant speed and the other one stationary (Couette flow), is related to the velocity of the moving plate and the distance between the two parallel plates Related formulas 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.
