2.  A fluid is a substance that has no fixed shape and
yields easily to external pressure; a gas or (especially)
a liquid.
Liquid =fluid

3. Viscosity or slimmines : It is the resilience when a
liquid is flowing.
This resilience can be high or low
Low viscosity High viscosity

4. A non-Newtonian fluid is a fluid that does not
follow Newton's Law of Viscosity. Most commonly,
the viscosity of non-Newtonian fluids is dependent
on shear rate or shear rate history. Some non-
Newtonian fluids with shear-independent viscosity.
