1. A=0 B=? n=? In an ideal fluid the viscosity should be equal to zero. 2. A=? B=? n=1 In a Newtonian fluid the flow behavior index is equal to 1 (Experimentally) 3. A=? B=? n≠1 In a non-Newtonian fluid the flow behavior index is bot equal to 1 This is the far that I could understand.

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
