Question:

A fluid sample is tested in a cup and bob viscometer that has a cup diameter of 2.25 in., a bob diameter of $2 \mathrm{in}$., and length of $3 \mathrm{in}$. The following data are obtained:

Rotation Rate (rpm)	Torque (dyn cm)
20	2,500
50	5,000
100	8,000
200	10,000

(a) Determine the viscosity of this sample.

(b) What model would provide the best representation of this viscosity function, and why?
