More example sentences

  • Electronics also compensate for changes in oil viscosity for consistent operation at all temperatures.
  • Once aspirated, due to their low viscosity and surface tension, they reach the dependent portion of the lung and cause a chemical pneumonia.
Synonyms
1.1A quantity expressing the magnitude of internal friction, as measured by the force per unit area resisting a flow in which parallel layers unit distance apart have unit speed relative to one another.
More example sentences

Origin

late Middle English: from Old French viscosite or medieval Latin viscositas, from late Latin viscosus (see viscous).
