Graph of shear stress (vertical axis) against shear rate (horizontal axis). Three lines extend straight up and to the right from the origin: Newtonian (straight), pseudoplastic (bending down) and dilatant (bending up). Two others extend from a point on the vertical axis above the origin: Bingham plastic (straight) and Bingham pseudoplastic (bending down).

The apparent viscosity of a fluid depends on the shear rate at which it is measured. The apparent viscosity of a dilatant fluid is higher when measured at a higher shear rate (η4 is higher than η3), while the apparent viscosity of a Bingham plastic is lower (η2 is lower than η1).
