They don't flow easily and consistently like water and other Newtonian liquids do.
2.
For non-Newtonian liquids, the apparent viscosity is not true viscosity.
3.
Non-Newtonian liquids have a large presence in the food industry.
4.
The ER fluid changes from a Newtonian liquid to a partially crystalline " semi-hard slush ".
5.
Liquids ( By that I mean Newtonian liquids ) like gasses cannot carry transverse waves ( s-waves ).
6.
For a Newtonian liquid, the apparent viscosity is the same as the true viscosity and the single shear rate measurement is sufficient.
7.
This effect is observed in numerous non-Newtonian liquids to a small degree, but is prominent in some materials such as molten polymers.
8.
This has a nice discussion of predicting the total flow rate through a circular pipe for a turbulent Newtonian liquid, and gives an approximate equation : volume flow rate = 49 * pi * radius ^ 2 * ( maximum speed ) / 60.
