A thick suspension is tested in a Couette (cup and bob) viscometer that has a cup radius

Question:

A thick suspension is tested in a Couette (cup and bob) viscometer that has a cup radius of $2.05 \mathrm{~cm}$, a bob radius of $2.00 \mathrm{~cm}$, and a bob length of $15 \mathrm{~cm}$. The following data are obtained:

Cup Speed (rpm)	Torque on Bob (dyn cm)
2	2,000
4	6,000
10	19,000
20	50,000
50	150,000

What can you deduce about (a) the viscous properties of this material, and (b) the best model to use to represent these data?
