a fluid in which flow and rate of shear are always proportional to the applied stress; such fluid precisely obeys Poiseuille law. Compare: nonnewtonian fluid.

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.

The extensional viscosity results show stretch-thinning behavior and an extensional viscosity that is 14-56 times higher than the shear viscosity of the suspension; for a Newtonian liquid, the extensional viscosity exceeds the shear viscosity by a factor of 3, that is, the Trouton ratio is exactly 3.
