If the relationship between the shear stress τ and the rate of shear strain \(\left( {\frac{{du}}{{dy}}} \right)\) is expressed as \(\tau = \mu {\left( {\frac{{du}}{{dy}}} \right)^n}\) then the fluid with exponent n > 1 is known as which one of the following?
1
Bingham plastic
2
Dilatant fluid
3
Newtonian fluid
4
Pesudoplastic fluid
