You have obtained data for a viscous fluid in a cup-and-bob viscometer that has the following dimensions: cup radius ¼ 2 cm, bob radius ¼ 1.5 cm, bob length ¼ 3 cm. The data are tabulated below, where n is the point slope of the log T versus log N curve.

(a) Determine the viscosity of the fluid. How would you describe its viscosity?

(b) What kind of viscous model (equation) would be appropriate to describe this fluid?

(c) Use the data to determine the values of the fluid properties that are defined by the model.
