Problem 12.1 which Y is 2.5104Pa,K is 4.5104Pas0.5, and n=0.5 at 200C. (a) Sketch the viscosity versus shear rate curve. (b) Sketch velocity and shear stress distributions in a long cylindrical tube through which this material is extruded. (c) What will the pressure drop be when this material is extruded in a long flat film die (60cm wide, 0.2cm thick, and 10cm long) at a volumetric flow rate of 100cm3/s at 200C
