FIGURE 5.38 Network flow 19. The graph in Figure 5.38 represents various flows that can occur through a sewage treatment plant with the numbers on the arcs representing the maximum flow (in tons of sewage per hour) that can be accommodated. Formulate an LP model to determine the maximum tons of sewage per hour that can be processed by this plant. model for the sewage treatment plant 8. 9 6 10 9 8 5 9 L 1 2 Jx A B C D E LL F G H Sewage Treatment Plant 3 Units Arcs.
