What Does viscosity Mean
The characteristic of viscous is known as viscosity . Something viscous is adhesive or pasty , differing from other states such as solid or liquid .
In this sense, it must be emphasized that something viscous is also usually related to the term mucus since both concepts make it clear that the element to which they refer is characterized by being slippery, sticky and also glutinous.
Among the most viscous products would be found from gelatin, various types of soaps, shampoos, gels and other beauty products. It should also be emphasized that there is a toy that is characterized by its viscosity and that it is it that has become the playmate of many children for decades.
Specifically, we are referring to blandiblu, a polymer that is characterized by being a “mass” of different colors that can be molded at the whim of each person to form all kinds of figures. It is also used by the smallest of the house to use it as a "weapon" in fun throwing battles with friends.
This viscous mass to play appeared in 1976 thanks to the Mattel company and caused a great stir in the world of children, and especially in the 80s as it became one of the most demanded entertainment for children.
Viscosity is used to refer to the counter force that a fluid exerts when faced with a tangential deformation . It is a property characterized by the resistance to flow that is generated from friction between the molecules .
Since all known fluids have some level of viscosity, the hypothetical fluid without viscosity (that is, with zero viscosity) is known as the ideal fluid .
More specifically, we can establish that viscosity is the main hallmark that identifies each and every one of the existing lubricants. Furthermore, in this case, in order to carry out the classification of the aforementioned lubricants based on it, it must be determined that it is clearly determined by both what the temperature is and what the pressure is.
Viscosity is measured by the friction that occurs between successive layers of a fluid . When dragging the surface of a fluid, the lower layers move more slowly than the surface as they are affected by tangential resistance. Viscosity, therefore, manifests itself in moving fluids (where tangential forces come into play)
When the viscosity is very high, the friction between the adjacent layers is pronounced and the movement is therefore weak.
The viscosity of fluids is measured through the coefficient of viscosity , a parameter that depends on temperature . The physical unit of dynamic viscosity is called the pascal-second , according to the International System of Units .
The poise , on the other hand, is the unit of the cegesimal system of units for dynamic viscosity . The name was established in honor of the French scientist Jean Louis Marie Poiseuille .
The kinematic velocity , finally, is the ratio of the dynamic viscosity and density. Its physical unit in the cegesimal system of units is known as stoke , while in the SI it is the square meter / second .
