Newtonian Fluid

A fluid is classified as being Newtonian if it conforms to NEWTON’s friction law, i.e. if viscosity remains constant with agitation or varying shear rate (i.e. viscosity is only affected by temperature changes) and its shear rate being proportional to the velocity gradient vertical to the direction of flow.

Of Newtonian fluid characteristics are e.g. the following:

water
oils
gases
mercury
alcohol
petrol

If it is not known whether a fluid is of Newtonian flow characteristics or not, it should be laboratory-tested."
