So far as experiment has gone, our conclusion is that the viscosity or fluid friction of the ether is zero.
The effect on gelation is also illustrated by the change of viscosity of the sol with time.
A low degree of viscosity will suffice to permit of movements so slow.
The quality of viscosity is practically absent in glacier-ice.
These limits depend on the coefficient of viscosity, which diminishes as the temperature increases.
The cream, having the heavier body or viscosity, will move more slowly.
For very rapid displacements the liquid on account of its viscosity behaves like a solid.
By the old gravity systems, the flow of oil depended largely upon its viscosity, or thickness.
The origin and cessation of rotation in fluids are due to their imperfection, their internal friction, their viscosity.
As yet there is not much known about the subject, and no one has devised a satisfactory means of measuring the viscosity.
viscosity vis·cos·i·ty (vĭ-skŏs'ĭ-tē)
The condition or property of being viscous.
The degree to which a fluid resists flow under an applied force, measured by the tangential friction force per unit area divided by the velocity gradient under conditions of streamline flow; coefficient of viscosity.
The resistance of a substance to flow. For example, water has a lower viscosity than molasses and flows more easily. Viscosity is related to the concept of shear force; it can be understood as the effect of different layers of the fluid exerting shearing force on each other, or on other surfaces, as they move against each other. Viscosity lies behind the skin friction component of drag. ◇ Kinematic viscosity is a measure of the rate at which momentum is transferred through a fluid. It is measured in stokes. ◇ Dynamic viscosity is a measure of the ratio of the stress on a region of a fluid to the rate of change of strain it undergoes. It is equal to the kinematic viscosity times the density of the fluid. It is measured in pascal-seconds or poises.
