viscosity (redirected from Ideal fluid)

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.

vis·cos·i·ty (v-sks-t)

n.

1. The condition or property of being viscous.

2. The degree to which a fluid resists flow under an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow; coefficient of viscosity.

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.

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.
