viscosity in British English
(vɪsˈkɒsɪtɪ)
nounWord forms: plural-ties
1.
the state or property of being viscous
2. physics
a.
the extent to which a fluid resists a tendency to flow
b. Also called: absolute viscosity
a measure of this resistance, equal to the tangential stress on a liquid undergoing streamline flow divided by its velocity gradient. It is measured in newton seconds per metre squared
Symbol: η. See also kinematic viscosity, specific viscosity
viscosity in American English

2.
a. Physics
the internal friction of a fluid which makes it resist flowing past a solid surface or other layers of the fluid: symbol, η
see also poise2

viscosity in Chemical Engineering
(vɪskɒsɪti)
noun
(Chemical Engineering: General)
The viscosity of a particular fluid is how easily it flows.
Where the viscosity is naturally high, such as polymer solutions and polymer melts, flow is normallylaminar.
Viscosity is a measure of flowability at particular temperatures.
The viscosity of a particular fluid is how easily it flows.
viscous
viscosity in Mechanical Engineering
(vɪskɒsɪti)
noun
(Mechanical engineering: Fluid engineering)
The viscosity of a particular fluid is how easily it flows.
Long stringy molecules may have a high viscosity because the molecules can become tangled, which prevents them from flowing.
Viscosity is a measure of flowability at particular temperatures.
The viscosity of a particular fluid is how easily it flows.
