In class, we introduced the concept of a Newtonian fluid. A Newtonian Fluid is one in which the stress and strain rate relationship is linear and related by the fluid viscosity. Answer the following equations about Newtonian and Non-Newtonian fluid models. 

a) With a Newtonian Model, indicate what the shear forces are on the x-face of a fluid element. 

b) With a Newtonian Incompressible Model, indicate what the normal force is on the x-face of a fluid element—show how this reduces to this equation from just a Newtonian model. 

c) Research the internet/literature and find three different models for Non-Newtonian fluids. Indicate the model equation and what applications to which these types of models may be more pertinent.
