As the test material has a constant viscosity irrespective of the shear rate for both test temperatures, it can be considered to be a Newtonian liquid.

Conclusions:
Under the conditions of the study, the dynamic and kinematic viscosities of the test material, at a test temperature of 20°C were 9125 mPa.s and 8839 mm²/s, respectively. The dynamic and kinematic viscosities of the test material, at a test temperature of 40°C were 871.4 mPa.s and 844.1 mm²/s, respectively.
As the test material has a constant viscosity irrespective of the shear rate for both test temperatures, it can be considered to be a Newtonian liquid.
Executive summary:

The dynamic and kinematic viscosities of shale oil heavy fraction, at a test temperature of 20°C, were 9125 mPa.s and 8839 mm²/s, respectively. The dynamic and kinematic viscosities of shale oil heavy fraction, at a test temperature of 40°C, were 871.4 mPa.s and 844.1 mm²/s, respectively.

As the test material has a constant viscosity irrespective of the shear rate for both test temperatures, it can be considered to be a Newtonian liquid.
