We explain what viscosity is and the types that exist. In addition, how is the viscosity of water and some examples of this property.
When we talk about viscosity we mean a property of fluids equivalent to the concept of thickness , that is, the resistance that certain substances have to flow, to suffer gradual deformations due to shear stresses or tensile stresses.
All fluids have viscosity (except ideal or superfluid fluids), due to collisions between their particles that move at different speeds. Thus, when the fluid is forced to move, said particles generate frictional resistance, retarding or preventing displacement.
This is because the liquid is composed of several layers of matter, which tend to hold together with each other even in the presence of external forces. For that reason viscous liquids do not generate splashes .
So a fluid with a very high viscositye will be very close to being a solid , since its particles are attracted with a force that prevents the movement of the upper layers. There are two types of viscositye: dynamics and kinematics.
The viscositye also depends on the nature of the fluid, and can be measured using a viscometer or rheometer. Liquids or gases can be used for this, and it is usually represented by the Greek letter μ for dynamics and by the letter v in the case of kinematics.
As said before, there are two types of viscositye: dynamics and kinematics . To this can be added the extensional and the apparent.
The viscositye of water at a temperature of 20 ° C is 1 x 10-3 Ns / m2. However, if it is at about 90 ° C, that is, close to boiling, its viscositye varies and decreases to 0.32 x 10-3 Ns / m2.
