**Fri Oct 11, 2019 12:29 pm**A power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid (time independent Non-Newtonian fluid) for which the shear stress, τ, is given by

τ = A(du/dy)^n +B

Where A, B and n are constants that depend upon the type of fluid and conditions imposed

on the flow. Comment on the value of these constants so that the fluid may behave as:

I) an ideal fluid

II) a Newtonian fluid

III)a non-Newtonian fluid

τ = A(du/dy)^n +B

Where A, B and n are constants that depend upon the type of fluid and conditions imposed

on the flow. Comment on the value of these constants so that the fluid may behave as:

I) an ideal fluid

II) a Newtonian fluid

III)a non-Newtonian fluid
