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
