Problem 2. A certain part of cast iron piping of a water distribution system involves a parallel section. Both parallel pipes have a diameter of 30 cm, and the flow is fully turbulent. One of the branches (pipe A) is 1500 m long and contains a fully open swing check valve while the other branch (pipe B) is 2500 m long and contains a fully open ball valve. If the flow rate through pipe A is 0.4 m³/s, determine the flow rate through pipe B. Assume the water temperature is 15°C and minor losses besides those caused by the valves are negligible. 30 cm 30 cm B Swing check valve 1500 m 0.4 m³/s 2500 m Ball valve
