1.  (5 points)  6.1 (Question about zero shear viscosity varying with molecular weight)
2.  (5 points)  6.6 (Which polymer has higher MW?)
3.  (5 points)  When an inert filler is added to a linear polymer, how does the viscosity curve (viscosity versus shear rate) change?  Explain with words and with a sketch.
4.  (5 points)  For a linear polymer of high molecular weight, what does G'(omega) look like?  Be sure to label the axes of your sketch.
5.  (20 points) 7.20  (Predict a newly defined material function for PL GNF)
6.  (30 points) 7.29 (unidirectional axial annular flow of a PL GNF)  Note that there are four parts to this question.
7.  (30 points) 7.30 (tangential annular flow of a PL GNF)  Note that there are three parts to this question:  1)  calculate velcity and pressure profiles; 2) Calculate the torque required; 3) Plot the velocity field.
