Determine the flow rates in each pipe in the pipe network system shown in Figure 3 below, using Hardy Cross method (n=2). You only need to perform 1 iteration. Given: Qin-Qout 1.2 m³/s. There are two series of assuming flow rates (X and Y). Select the correct series and give reasons for your choice. Use the selected series as the initial assumed flow rates for the iteration. The required information are given in the following table:
