2.) A capillary rheometer is used to measure viscosity. A pressure transducer records the pressure drop delta P across the die, and the die capillary has a diameter of 2 mm. Experiments are carried out at three volume flow rates Q, for dies of each of three lengths l. The following is a table of values of delta P (in MPa) measured for polupropylene at 190 C. For each flow rate Q find the apparent viscosity, assuming Newtonian behaviour.
