Water flows through a pipeline whose diameter contracts from 45 cm at A to 30 cm at B after which it forks into two branches, as shown in Figure P5 .6. The first branch is 15 cm in diameter discharging at C, and the second branch is 22.5 cm in diameter discharging at D. The velocities at A and Dare 1.8 m/s and 3.6 m/s, respectively. What would be the velocities and discharges at sections B and C?
