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

As above, the equivalent Newtonian viscosity is defined as that giving the same pressure gradient at the same flow rate, and so, from Eq.

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.
3%, and those for the model tangent to the viscosity curve at the equivalent Newtonian viscosity [[mu].

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.
0] is the Newtonian viscosity and [eta]* is the complex viscosity.
However, in the case of the APP145 sample, an increase of [eta]* is detected as frequency is lowered, which impedes the determination of the linear or Newtonian viscosity [[eta].
Considering that the Newtonian viscosity of pure bitumen at this temperature is 400 Pa s, the viscosity of the blend is lower than that which corresponds to a simple additive rule:
