Meaning & Definition of word "Viscosity"
to
Viscosity
/vɪˈskɒsɪti/
noun:
- 1. A measure of a fluid's resistance to flow or deformation; specifically, the thickness or stickiness of a liquid.
- Example: The viscosity of honey is higher than that of water, making it flow more slowly.
- 2. The quality of being viscous; the state or condition of being thick and sticky.
- Example: In engineering, the viscosity of lubricants is crucial for ensuring efficient machinery operation.
- 3. In physics, viscosity is a property that quantifies the internal friction in a fluid.
- Example: The viscosity of the oil affects how it circulates in the engine under different temperatures.
- 4. A physical property that describes resistance to shear or tensile flow.
- Example: The shear viscosity of the material was tested to ensure it met the required specifications.
Etymology
From Latin 'viscositas' meaning 'sticky'.
