viscosity    音标拼音: [vɪsk'ɑsəti]
n. 粘质,粘性

粘质,粘性

viscosity
粘性

viscosity
n 1: resistance of a liquid to shear forces (and hence to flow)
[synonym: {viscosity}, {viscousness}]

Viscosity \Vis*cos"i*ty\, n. [Cf. F. viscosit['e], LL.
viscositas.]
1. The quality or state of being viscous.
[1913 Webster]

2. (Physics) A property possessed by a viscous fluid, being a
resistance to the forces causing a fluid to flow, caused
by interactions between the molecules of the fluid and
between the fluid and the walls of the conduit through
which it moves; also, a measure of such a property.
[1913 Webster PJC]

  • Viscosity - Wikipedia
    Viscosity is a measure of a fluid 's rate-dependent resistance to a change in shape or to movement of its neighboring portions relative to one another [1] For liquids, it corresponds to the informal concept of thickness; for example, syrup has a higher viscosity than water [2]
  • Viscosity | Definition, Facts, Formula, Units, Examples | Britannica
    What is viscosity? Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another Viscosity denotes opposition to flow
  • Viscosity: Definition, Examples, and Formula - Science Facts
    Viscosity is a physical quantity that describes a fluid’s resistance to flow It is a property that resists the relative displacement of the different layers of the fluid
  • Viscosity: Why Liquids Resist Flow and the Role of Intermolecular Forces
    Learn how viscosity measures a liquid’s resistance to flow, why “thick” liquids like syrup move slowly, and how intermolecular forces and molecular structure impact flow rate
  • What is Viscosity? - GeeksforGeeks
    Viscosity refers to a fluid's resistance to flow, indicating how easily it deforms or changes shape when exposed to stress A high viscosity means the fluid flows slowly, such as honey, whereas a low viscosity allows the fluid to flow more freely, like water
  • Viscosity Definition and Examples - Science Notes and Projects
    By definition, viscosity is a fluid’s resistance to flow or deformation A fluid with a high viscosity, such as honey, flows as a slower rate than a less viscous fluid, such as water
  • Viscosity – The Physics Hypertextbook
    Informally, viscosity is the quantity that describes a fluid's resistance to flow Formally, viscosity is the ratio of shearing stress to velocity gradient

    In this article, you will learn what viscosity is, how it is measured, and the viscosity equation of a fluid You’ll also explore the reasons why viscosity is important
  • What Is Viscosity? The Resistance to Flow Explained
    Viscosity is a property of all fluids, encompassing both liquids and gases, that determines a material’s resistance to flow or to a change in shape This property can be understood as the fluid equivalent of internal friction, governing how easily a substance moves or deforms when subjected to an external force A fluid with high viscosity, such as honey or molasses, flows slowly and is
  • 9. 7: Viscosity - Biology LibreTexts
    Viscosity is a fluids resistance to flow This page details why certain liquids flow easily while others are slow as molasses
