# Formula: Fluid Between Two Parallel Plates Viscosity    Velocity    Inner surface    Force    Distance

## Viscosity

Unit
The greater the viscosity of a liquid, the more viscous the liquid. The liquid is located (for the use of this formula) between two plates parallel to each other.

Liquid Viscosity $$\eta$$
Olive oil$$108 \cdot 10^{-3} \, \frac{\mathrm{kg}}{ \mathrm{m}\cdot \mathrm{s} }$$
Honey$$10\,000 \cdot 10^{-3} \, \frac{\mathrm{kg}}{ \mathrm{m}\cdot \mathrm{s} }$$
Glycerin$$1500 \cdot 10^{-3} \, \frac{\mathrm{kg}}{ \mathrm{m}\cdot \mathrm{s} }$$
Water$$1.008 \cdot 10^{-3} \, \frac{\mathrm{kg}}{ \mathrm{m}\cdot \mathrm{s} }$$
Tar$$100\,000 \cdot 10^{-3} \, \frac{\mathrm{kg}}{ \mathrm{m}\cdot \mathrm{s} }$$

## Velocity

Unit
One of the plates between which the liquid is located is displaced in parallel. The liquid directly at the shifting plate has a maximum velocity $$v_0$$.

## Inner surface

Unit
The surface of one side of the plate.

## Force

Unit
A force $$F$$ is applied parallel to a plate, resulting in a shear stress $$F/A$$ on the liquid.

## Distance

Unit
Distance between the two plates.
