Graph the constraint upon the wall depending on the sharing rate, for increasing rotation speeds. Analyze a possible hysteresis effect. Graph the apparent viscosity depending on the sharing rate. Conclude. Few questions to wonder: For a Newtonian fluid, how is the variation of the viscosity according to the temperature? - Does the curve need to pass by 0? - Does the analyzed non-Newtonian fluid have a threshold constraint? If yes, estimate it. -
