In a horizontal pipe system, water flows successively through three circular sections: section A (diameter 6.0cm), a throat section B (diameter 3.0cm), and an exit section C (diameter 8.0cm). The steady volume flow rate is 0.020m3s−1. Determine:
a. (i) the speeds of water in sections A, B, and C
b. (ii) the ratio of throat speed to entry speed
c. (iii) the ratio of exit speed to throat speed
