what viscocity means?

Answer 1

Viscosity (not viscocity)

This question is often best answered by example. Imagine a styrofoam cup with a hole in the bottom. If I then pour honey into the cup I will find that the cup drains very slowly. That is because honey's viscosity is large compared to other liquids' viscosities. If I fill the same cup with water, for example, the cup will drain much more quickly.

Viscosity is a measure of a fluid's resistance to flow. It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion.

Gases also have viscosity, although it is a little harder to notice it in ordinary circumstances.

Answer 2

Viscosity is a measure of the resistance of flow of a fluid. A liquid like hexane has a very low viscosity and so will flow through a small tube very easily and quickly. On the other hand, a liquid like glycerol or honey has a high viscosity and flows slowly. The viscosity of a liquid is related to the strength of the intermolecular attractions between molecules of the liquid. The stronger those forces are, the higher the viscosity of the liquid.

Answer 3

For easy of understanding Viscosity can be defined as a measure of a fluid's resistance to flow. It describes the internal friction of a fluid when tried to flow for some purpose using some mechanism. When a fluid is flowing its molecules are sliding over its different layers. (You will surprise to know that velocity of a flowing liquid is different on top layers, middle portions and bottom portions - because it gets different amounts forces to flow.) A fluid with higher viscosity resists motion more strongly because its molecular makeup gives it a lot of internal resistance. A fluid with low viscosity flows easily because its molecular makeup results in very little resistance when it is in motion. This resistance has some relation with its structural formula, molecular weight and other physicals conditions like temperature. Gases also have viscosity, although it is a little harder to notice it in ordinary circumstances.

Answer 4

Viscosity is a measure of the resistance of a fluid to deform under shear stress. It is commonly perceived as "thickness", or resistance to flow. Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. Thus, water is "thin", having a lower viscosity, while vegetable oil is "thick" having a higher viscosity. All real fluids (except superfluids) have some resistance to shear stress, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid !

All real fluids (except superfluids) have some resistance to shear stress, but a fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid (Symon 1971).

Answer 6

Viscosity is the 'Resistance to Flow' of a liquid.
Thick liquids like Treacle and Honey have a High Viscosity.
'Thin' liquids like Water and Gasoline have a very Low Viscosity.

Answer 7

Viscosity is the measure of friction between adjacent layers of a fluid. A fluid is assumed to be consist of layers moving with different velocities.The force of friction between the adjacent layers is directly proportional to the velocity gradient and the constant of proportionality in this equation gives measure of viscosity. The unit most commonly used for viscosity is poise.

Answer 8

Viscosity describes a fluid's internal resistance to flow. It's a measure of how "thick" a fluid is.

Something that has a high viscosity is honey - thick

Something that has a low viscosity is ether - low

Answer 9

Viscosity is the property of fluid. The velocity of fluid defends off on the viscosity of the fluid.viscosity is inversely proportional to velocity.

Answer 10

Viscosity:
High viscosity means the melt is thick and resistance to flow is high. ... two liquid layers when they are moved relative to each other is called viscosity.
