Question: Power Law Model = m ? n where - m = Consistency index - n = Power law index If n = 1 , then

Power Law Model
=m?n
where
-m= Consistency index
-n= Power law index
If n=1, then m=, then it is Newtonian fluid
If n>1, then it is shear-thickening fluid
If n1, then it is shear-thinning fluid
Exercise: re-write the above equation in terms of viscosity as a function of strain rate?
Power Law Model =m?n where -m= Consistency index -n= Power law
