Problem Statement A 50 ft diameter tank is located in a city to supply drinking water for a small community. The average demand at each junction in cfs are shown in

Figure 1. The tank (20 ft high: 50 ft diameter; 10 ft initial level) is located 400 ft above the city. The tank supplies water with a constant flow of 4 cfs during the day. All the nodes in the network are located at 0 ft elevation. All pipes have roughness coefficient C=100. Use Hazen-Williams formula for calculations and neglect minor losses. The lengths and diameters of all pipes are fixed and are given in Table 1.
