A capillary rheometer is used to measure the viscosity of a fermentation broth. The capillary has an internal diameter of 0.5mm and is 6cm long. A pressure transducer is used to monitor the pressure drop across the capillary under different flow rates. The different flow rates tested, their corresponding shear rate and recorded pressure drop are shown in the table below. a. What type of flow would you expect to observe in the capillary rheometer? [6 marks] b. Calculate the apparent viscosity of the broth for each flow rate and determine the type of fluid. Check any assumptions made. [20 marks] c. Plot the rheogram and determine analytically the rheological parameters of this fluid. [16 marks] d. Explain which changes in the fermentation broth might have caused the rheological properties observed. [8 marks]
