the state or quality of being viscous.

Physics. the property of a fluid that resists the force tending to cause the fluid to flow. the measure of the extent to which a fluid possesses this property.

the state or property of being viscous

(physics) the extent to which a fluid resists a tendency to flow 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 η See also kinematic viscosity, specific viscosity
