At low flow rates the pressure drop Δ P is related to the flow rate Q by the Hagen-Poiseuille equation: Δ P = 8 μ ℓ π r 4 Q. where ℓ … WebThe viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress.. For further definitions, go to Absolute (dynamic) and kinematic viscosity. Absolute or dynamic … WebThe viscosity is independent of the shear rate. Non-Newtonian fluids do not follow Newton’s law and, thus, their viscosity (ratio of shear stress to shear rate) is not constant and is dependent on the shear rate.
