VISCOSITY OF LIQUIDS WITH VIDEO DEMONISTRATION

HEY THERE HI TODAY I GOT A VIDEO FOR MY FRIENDS WHO ARE FOND OF CHEMISTRY

THIS IS THE VIDEO THAT CAN DESCRIBE WHAT IS VISCOSITY .

NOW FOR THOSE FRIENDS WHO ARE UNABLE  TO OPEN THE YOUTUBE MUST CLICK ON THE LINK BELOW

DESCRIPTION OF THIS VIDEO IS :


NOW LET SUPPOSE THAT THE FIRST VESSEL CONTAINS MILK AND OTHER CONTAINS HONEY .well now what happens was that when a solid was made to drop into milk it strikes and milk splashes out because it is less viscous .
we can say that
viscosity is inversely proportional of the FLOW of liquid

as honey is more viscous than milk so when a solid cube strikes honey it does not splashes and
it just sinked.

 

 

 

 

 

 

Viscosity is a measure of the resistance of a fluid which is being deformed by either shear stress or tensile stress. In everyday terms (and for fluids only), viscosity is "thickness" or "internal friction". Thus, water is "thin", having a lower viscosity, while honey is "thick", having a higher viscosity. Put simply, the less viscous the fluid is, the greater its ease of movement (fluidity).[1]

Viscosity describes a fluid's internal resistance to flow and may be thought of as a measure of fluid friction. For example, high-viscosity felsic magma will create a tall, steep stratovolcano, because it cannot flow far before it cools, while low-viscosity mafic lava will create a wide, shallow-sloped shield volcano.

With the exception of superfluids, all real fluids have some resistance to stress and therefore are viscous. A fluid which has no resistance to shear stress is known as an ideal fluid or inviscid fluid. In common usage, a liquid with the viscosity less than water is known as a mobile liquid, while a substance with a viscosity substantially greater than water is simply called a viscous liquid.

The study of flowing matter is known as rheology, which includes viscosity and related concepts.



Viscosity
A simulation of substances with different viscosities. The substance above has lower viscosity than the substance below
Common symbol(s): η, μ
SI unit: Pa·s = kg/(s·m)
Derivations from other quantities: μ = G·t
