Water moves through three sections of a pipeline arranged in series:
• Section 1: circular pipe, diameter 6.0 cm, speed 1.0 m s⁻¹
• Section 2: square duct, side 4.0 cm
• Section 3: circular pipe, diameter 3.0 cm
a. (a) Calculate the speed of water in Section 2.
b. (b) Calculate the speed of water in Section 3.
c. (c) Find the ratio of the speeds in Section 3 to Section 1.
