newton - derived unit of force in the SI system.
Newton disk - a disk on which there are seven colored sectors, which, when rapidly rotated, appear white.
Newton law - the attractive force between any two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Synonym(s): law of gravitation
Newton rings - colored rings on thin surfaces.
newtonian aberration - the difference in focus or magnification of an image arising because of a difference in the refraction of different wavelengths composing white light. Synonym(s): chromatic aberration
newtonian constant of gravitation - a universal constant relating the gravitational force, attracting two masses toward each other when they are separated by a distance.
newtonian flow - the type of flow characteristic of a newtonian fluid.
newtonian fluid - a fluid in which flow and rate of shear are always proportional to the applied stress.
newtonian viscosity - the viscosity characteristics of a newtonian fluid.

A local power-law model is constructed as the tangent to the viscosity curve at the equivalent Newtonian viscosity for the power-law model which follows from Eqs.
6, there is a radial position where the viscosity equals the equivalent Newtonian viscosity and the shear rate is given by the C-Y model.
As above, the equivalent Newtonian viscosity is defined as that giving the same pressure gradient at the same flow rate, and so, from Eq.
e] is the Newtonian viscosity giving the same pressure gradient at the same flow rate.
The switching in the truncated power-law model between Newtonian and power-law behavior is abrupt and occurs where a local equivalent viscosity equals a limiting Newtonian viscosity to ensure that the pressure gradient is continuous.

h] as determined by the above decision making process, and consequently the equivalent Newtonian viscosity is between [[micro].
Introducing the equivalent Newtonian viscosity then gives the following expression for the outer cavity pressure P, and an expression for inner cavity pressure [bar.
An effective way to implement the truncated power law model is to switch between Newtonian and power-law flow when both give the same pressure gradient using an equivalent Newtonian viscosity.
Again, the model predictions using a constant Newtonian viscosity are shown for each polymer using dashed curves.
