Viscosity is the property of a liquid by virtue of which it tends to resists its own flow or we can understand it as a resistance which liquid feels when they experience any sort of change in their shape.

You can get a clear understanding of viscosity by an example, suppose if we have two liquids water and honey. And if we allow them to flow we will notice that the speed of the flow of water is higher and the speed of flow if honey is slower when both are compared with each other. This is due to the fact the water is more viscous than water. Hence we can get an idea with this the liquids which have a slow rate of flow are more viscous and the liquid which is fast inflow have less viscosity

Viscosity is also referred as the thickness of the fluid when all go to the molecular level, it is the viscosity which is actually the interaction of molecular fluid or you can say that it the fraction which is between the molecules of the fluid which is created when they are moving

The fluids which do not have any sort of resistance to their own flow are considered as the ideal fluid or we can say them inviscid fluid. but you can find Zero viscosity at very low temperature that in superfluid’s

**Viscosity dependence **

- The viscosity of any liquid depends on the density of the liquid, As the density of the liquid goes high the viscosity of the liquid goes high and as the density of the liquid goes down the viscosity goes down.
- The viscosity of any liquid also depends on the temperature of the liquid, as the temperature of the liquid goes high, the viscosity of the liquid start decreases.
- The viscosity of the liquid can also be affected by dilution.

**Measurement **

- the viscosity of any fluid is measured in terms of its resistance to the deformation
- you can use various methods in order to measure viscosity one of the best way to do is to use viscometer which you can easily get at the market
- There is one popular method which is a DIY method, in this method we take one fluid whose velocity is known as the fluid whose viscosity is unknown. And comparing the viscosity of this fluid we calculate the viscosity of an unknown fluid.

**UNITS **

The unit of viscosity is poise or Pa.s or kg/m/s. the unit poise is given in honor with famous scientist which is named Jean Leonard Marie Poiseuille

The SI unit of the viscosity is M*M/s where are you look in CGs system you will find it as stokes which is named in the honor of George Gabriel Stokes.

Another unit Reyn is used for viscosity, this is a British unit of dynamic viscosity and in addition to this, there is a term the viscosity index which used to find out the change of viscosity with temperature.

The viscosity is the reciprocal of fluidity. Which you can find using a relation as F=1/u, with this relation we can find the fluidity the property which allows liquids to flow.
