Rainwater flows steadily through the galvanized-iron pipe, discharging into the atmosphere as shown in the figure. The non-circular pipe cross-section is rectangular (height of 0.1 m and a width of 0.2 m) and does not change in dimensions, has a vertical section that becomes a horizontal section through a short-radius 90-degree elbow. The velocity at the free surface in the gutter may be assumed negligible. For the design conditions shown (H = 3.0 m, L = 2.1 m, h = 0.15 m), determine the resulting discharge through the pipe, including minor losses in your analysis
