The importance of viscosity
The importance of viscosity is the unit of measurement for the viscosity of a fluid. Fluids are substances that deform fluent. In the science of gases and liquids to drop underneath it.
- The greater the viscosity of a fluid is, the thicker this is. The viscosity is low, the substance, however thin.
- Any liquid is made up of particles. These are linked either closely or not. They are close to each other, they are immovable. Here one speaks of internal friction.
- The internal friction can be described with the movement of the two superposed toothed molecule layers. Because molecules flow and touch in the matter constantly.
- In order to overcome the interlocking of the molecules at this Flow, it requires a certain force. The viscosity defines this power in connection with the Fluid and its properties.
- Water , for example, has a viscosity of 1.0 η. Grape juice, however, from 2 to 5 h.
- The term goes back to the Plant of the mistletoe (Viscum). From this early bird was won glue. Therefore, viscous means so much as 'tough as bird glue'.
