2 O 3 /water nanofluid at different temperatures.
The plot between the applied strain rate and the shear stress at three different
temperatures of 6°C, 30°C and 75°C for the NF is shown in Figure 4.22. It can be seen
that the curves are straight lines passing through the origin. This behaviour represents the
NF as a Newtonian fluid for the given shear rates, implying that the viscosity of the fluid

represents the viscosity.
