i. ii. iii. iv. v. Demonstrate that this flow is rotational, i.e., fluid elements experience rotational motion. Explain why your answer in (i) is correct even though fluid elements move in straight parallel paths in this flow. Calculate the locations of particles A and B, i.e., yA and yB shown in Fig. 4 above. Calculate the rates of rotation experienced by particles A and B. Do particles A and B experience the same rate of rotation? Why? (30 Marks)
