Law of viscosity formula

WebViscosity is a physical property of fluids.It shows resistance to flow. In a simple example, water has a low viscosity, as it is "thin". Syrup and tar, on the other hand, have a high viscosity, as they are "thick".A way to test for viscosity is the speed at which the substance runs down a slope. Syrup would reach the bottom very slowly, and water would be much … WebThis power-law viscosity corresponds to the viscosity of a Newtonian fluid which would have given the same pressure drop Δ p / L along a capillary. For a power-law constitutive relation μ = K˙γn - 1 Equation (9) can be inverted to obtain an effective shear rate ˙γeff ˙γeff = (3n + 1 4n) 1 n - 1( Δ pR 2KL)1 n. (10)
