IntroductionIn this section of the essay the author will define the meaning of Newtonian fluids,
give examples and also talk about how temperature and pressure can have an
impact on the performance of the Newtonian fluids.
Newtonian Fluids
A Newtonian fluid is nothing but the flow performance of liquids with a relation to the
following: shear stress and also shear rate. The viscosity of a Newtonian fluid stays
continuous and the quantity of shear put on will not change the viscosity.

Analysis and Conclusion
In conclusion, I think that it is important to know how Newtonian fluids perform
and how their performance get affected when there is shear stress acting on
those type of fluids.
