I have a a strain rate as well as the shear rate of a flowing material, do these quantities have any relation? Can I compute the viscosity using these?
Please explain the difference between each of these terms with physical equations and units.

Some sources say it is treated as Newtonian as ethylene glycol has a higher viscosity than water, which affects the flow characteristics in simulations. But some also say it is non-Newtonian.
