  • n. The quality or state of being viscous.
  • n. 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.

from The Century Dictionary and Cyclopedia

  • n. The state or property of being viscous; the quality of flowing slowly, as pitch or castor-oil. Such liquids are commonly sticky, but this is no part of the viscosity.
  • n. In physics, internal friction, a resistance to tire motion of the molecules of a fluid body among themselves: opposed to mobility.
  • n. A glutinous or viscous body.

  • A molasses-like liquid, although not as viscous as the real thing, can be made by slowly boiling 6-8 or so piloncillos in a liter or so of water, until they dissolve and the desired viscosity is achieved.

  • As you practice, it gives you feedback on your progress, not only telling you how fast you're going, and how accurately you type, but it even looks at your "viscosity" - the amount of time you spend hesitating between characters as you type.

  • An alternative way to approach this closure problem would be to run your code with variations in viscosity models and parameter values and pick the set that gave you outputs that were in good agreement with high-entropy functionals (like an average solution state, there’s many ways to get the same answer, and nothing to choose between them) for a particular set of flows, this would be a sort of inverse modeling approach.

  • Similarly, the liquid’s viscosity is important: Pure water droplets aren’t strong enough to hold together and would break apart, and liquids that are too thick will move too slowly.
