I am aware that for using the power law viscosity model, we need to find n and K. I am aware some rheometers can calculate it for you but how to do determine them using viscosity vs shear rate data? Thank you.
Dear Mohammed Bakir, there are standard procedures to do that, such as ASTM. Please check the following documents. My Regards

Great thank you

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.
