Question

In reality the capillary rheometer has a 20 kN load cell that pushes the material down. The diameter of the reservoir is actually 25 mm and the max velocity of the piston is 1200 mm/min. Assume the material is molten corn starch that has a density of 1200 kg/m3, and heat capacity is 3 kJ/(kg*C). a) what is the max temperature rise of the material? b) Can you neglect the velocity in the reservoir, why or why not?
