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

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.
