viscosity

 [vis-kos´ĭ-te]
resistance to flow; a physical property of a substance that is dependent on the friction of its component molecules as they slide by one another.

vis·cos·i·ty

(vis-kos'i-tē),
In general, the resistance to flow or alteration of shape by any substance as a result of molecular cohesion; most frequently applied to liquids as the resistance of a fluid to flow because of a shearing force.
[L. viscositas, fr. viscosus, viscous]

viscosity

/vis·cos·i·ty/ (vis-kos´ĭ-te) resistance to flow; a physical property of a substance that is dependent on the friction of its component molecules as they slide by one another.

viscosity

[viskos′itē]
Etymology: L, viscosus, sticky
the ability or inability of a fluid solution to flow easily. A solution that has high viscosity is relatively thick and flows slowly because of the adhesive effect of adjacent molecules. - viscid, viscous, adj.

viscosity

An MRI term for a measure of a fluid’s resistance to deformity by shear or tensile stress, which affects its mobility and therefore its intensity in an image.

viscosity

The tendency of a fluid to resist flow or the quality of resistance to flow; viscosity is measured with a viscometer to assess hyperviscosity syndromes associated with monoclonal gammopathies, rheumatoid arthritis, SLE, hyperfibrinogenemia Ref range 1.4-1.8 relative to water. See Apparent viscosity. Cf Specific gravity.

viscosity

  1. the property of stickiness by which substances resist change of shape.
  2. a measure of the ease with which layers of fluid pass each other.

viscosity

the property of a fluid medium that provides resistance to motion of the fluid itself or of an object moving through it. Also can be considered to be friction within fluids.

viscosity

resistance to flow/deformation, due to molecular cohesion

viscosity (vis·kôˑ·s·tē),

n the degree of resistance of a liquid to flow.

vis·cos·i·ty

(vis-kos'i-tē)
In general, the resistance to flow or alteration of shape by any substance as a result of molecular cohesion.
[L. viscositas, fr. viscosus, viscous]

viscosity (viskos´itē),

n the ability or inability of a fluid solution to flow easily. High viscosity indicates a slowflowing fluid.

There are many equations that can be used to describe shear viscosity.
Similar to the experimental data, the results show that with increasing hLCB, the low shear viscosity increases while the high shear viscosity decreases, at constant molecular weight.
5 is likely reflecting more in real extensional viscosity changes than is reflected in the traditional multiple of 3x a steady state shear viscosity of a Newtonian fluid or in the [M.
However, this model can be used only for a limited range of shear-rates since it leads to an infinite shear viscosity for very small shear rates.
For this purpose, it was implied that the complex viscosity as function of angular frequency in oscillatory shear is adequate to the shear viscosity as function of steady shear following the Cox-Merz correlation.
As polymers are viscoelastic materials, extensional viscosity (also known as elongational viscosity) as well as shear viscosity should be measured for a more complete understanding of a polymer's properties.
1) Fluid properties such as surface tension, shear viscosity, viscoelastic behavior, and extensional viscosity have been studied and related to the sprayability of systems in complex coating systems.
Shear viscosity data were generated using the capillary rheometer (figure 15).

Viscosity measurements based on ASTM D4287, "High Shear Viscosity Using a Cone/ Plate Viscometer," showed that the viscosity of the paint at 12,000 [sec.
It acts as a high shear viscosity builder, which allows for reduction of KU builders such as cellulose ethers and provides one-coat coverage capability.
The curing bladder compounds mixed in this study were tested for filler dispersion, shear viscosity, tensile properties, failure properties (fatigue life and tear) and thermal conductivity.
