figure 1.5 Rasht city Water Pipeline pilot Research (with surge tank and in leakage
condition) Water flow decreased from 3000(l/s) to 2500(l/s).
In this chapter, location and rate of UFW in the pipeline was investigated. Loca-
tion and rate of UFW in the pipeline are shown in Figure 1.5. Minimum Pressure line
curve which was under the Transmission Line profile, located in vicinity of 50,000
m³ reservoir. Hence, there is a minus pressure in the zone of Transmission Line, in
which it must be removed from the system. Maximum Transient Pressure line was
completely over the steady flow pressure line. Maximum Pressure in the system was
156.181(m) .This pressure is too high for old pipes and it must be considered as a haz-
ard for piping system. (Table 1.8-1.10).
