污水管道系统的设计

作业题 请运用水力计算图, 管段进行水力计算: (1)已知:设计管段长L=150m,地面坡度I=0.0036,设计流量Q=29L/s,上游管道直径是300mm,充满度h/D=0.55,管底高程为44.65m,地面高程为46.60m.求设计管段的直径和管底高程. (2)已知:设计管段长L=130m,地面坡度I=0.0014,设计流量Q=56L/s,上游管道直径是350mm,充满度h/D=0.59,管底高程为43.6m,地面高程为45.48m.要求设计管段内充满度h/D=0.65.求设计管段的直径和管底高程. (3)已知:设计管段长L=50m, I=0.008, Q=30L/s(上端地面高程45.00,下端地面高程44.60),上游管道直径是300mm, h/D=0.5,下端管底高程为44.00m,最小覆土厚度不得小于0.7m.求设计管段的直径和管底高程. 流域范围大,且地形较平坦 Evaluation only.
