Using the elevation of the suction to the pumps as the datum, develop modified pump curves for Pumps A and B. These modified curves should show, for each pump, the head at the end of the 400ft line as a function of the flow rate through the pump and the corresponding pipe. Show the modified curves on a copy of the given plot. These modified curves are convenient for this analysis, because they characterize the parts of the system where the water that passes through Pump A experiences different conditions from the water that passes through Pump B; downstream of the point characterized by these pump curves, the flow that has passed through Pump A is indistinguishable from the flow that has passed through Pump B. On the plot, draw a curve that represents the modified head vs. discharge for the combination of Pumps A and B. Draw the modified system curve on the plot and determine the total discharge to reservoir 2 when both pumps are operating. What fraction of the total discharge to reservoir 2 passes through Pipe 4?
