Draw system head-discharge curves for the simplified water system diagramed in Figure 4-...

Draw system head-discharge curves for the simplified water system diagramed in Figure 4-9. The lowest anticipated system head-discharge curve is when the hydraulic gradient at the load center is 99 ft, as drawn in Figure 4-8. The highest anticipated head-discharge curve is when the discharge at B is zero and the hydraulic head at C is 140 ft.
