Your boss gives you a sample of "gunk" and asks you to measure its viscosity. You do this in a cup and bob viscometer that has an outer (cup) diameter of 2 in., an inner (bob) diameter of $1.75 \mathrm{in}$., and a bob length of $4 \mathrm{in}$. You run the viscometer at three speeds and record the following data:

Rotational Velocity, $\boldsymbol{\Omega}(\mathbf{r p m})$	Torque on Bob, $\boldsymbol{T}(\mathbf{d y n} \mathbf{~ c m})$
1	10,500
10	50,000
100	240,000

(a) How would you classify the viscous properties of this material?

(b) Calculate the viscosity of the sample in $\mathrm{cP}$.

(c) What viscosity model best represents these data, and what are the values of the viscous properties (i.e., the model parameters) for the model?
