VISCOSITY OF LIQUID
Understanding the fluid viscosity (liquid) is caused by the friction of the moving fluid, or a solid object moving in the fluid. The magnitude of the friction is also referred to as the degree of viscosity of liquid substances. So the bigger the viscosity of the liquid, then the hard solid object moving in the liquid. Viscosity in molten substances, which act is the force of cohesion between particles of liquid.
The viscosity can be expressed as a penal aliaran the fluid which is the friction between the molecules of the liquid molecules – one with the other. A type of fluid that flows easily, it can be said to have a low viscosity, and otherwise difficult material flows are said to have a high viscosity.
The viscosity of a fluid is the nature that shows large and small stand in a fluid against friction. The fluid that has a low viscosity, such as water has in custody against a smaller friction compared with the fluid which has greater viscosity.
These symptoms can be analyzed with introduced a quantity called viscosity or viscosity (viscosity). Therefore, the viscosity is related to the relative motion between the parts of the fluid, then this quantity could be viewed as a measure of the level of difficulty of the fluid flow. The greater the viscosity of a fluid is the fluid that flows more difficult. The existence of a substance dissolved macromolecules will raise the viscosity of the solution. Even at concentrations of rendahpun, the effect is great because large molecule affects the fluid flow on long distances.The viscosity of a liquid or solution is a pure index barriers to the flow of fluids. The viscosity can be measured by measuring the rate of flow of fluid through a tube-shaped cylinders. This way is one of the easiest way and can be used for either liquid or gas. The flow of the liquid can be grouped into two types. The first is "laminar" flow or flow of a viscous, which generally describes the small flow rate through a pipe with a small diameter. The other stream is a stream of "turbulent", which depicts a large flow rate through a pipe with a larger diameter.
In interpreting the viscosity measurement, there is a lot of complexity measurement. most (not all) are based on empirical observations, and the determination of the molar mass is usually based on a comparison with a standard sample.
One complexity in measurements in the measurement of intensity are: in some cases, it turns out that the fluid is non-Newtonian, that is viskositasnya change as the flow rate increases. A decrease in viscosity with increasing flow rate showed a long Rod-like molecules, which flow-oriented advertising, making mutual slid past each other more freely. In some cases, the pressure caused by the flow becomes very large, so that the long molecules are disjointed. This brings further consequences on the viscosity.

Look
at the image below, where a fluid layer placed between two boards, one
Board moves, while one Board again silent. Fluid in contact with the
respective boards due to the style of the adhesion between the Board and
the fluid, so that the top is moving with velocity v, the fluid section
above also move with the same speed. Meanwhile, the Board is in contact
with the fluid are also quietly silent. Thus, there is a variation in
the speed of fluid, from zero to v. If the speed v is divided with a
thick layer of l, then the magnitude of the gradient is called

constant which is narrow. The pressure along the pipeline would be
konsatn, but we observe fall of pressure when we move along the
direction of flow. A difference of pressure needed to push the fluid
through a horizontal pipe. This pressure difference due to the style of
gesekkan fluid layer provided on the reconciled and style gesekkan given
by each layer of fluid moving with the speed of his neighbors, gesekkan
styles is called viscosity.
