Maximum pressure in entire network is 126.7 mH at point P4:J3 of Rasht city
Water Pipeline. Minimum pressure in entire network is -0.9 mH at point P25:J28 of
Rasht city Water Pipeline. Elapsed time was 12 s for Hammer - Version 07.00.049.00
software. (Table 2.5-2.6) [17]
2.3.1 Comparison of Present research results with other expert's research
Comparison of present research results (water hammer software modeling) with other
expert's research results shows similarity according to flowing:
Jaime Suárez Acuña and Chaudhry have obtained pressure heads by the steady and
unsteady friction model. Comparison shows similarity in present Research and Jaime
Suárez Acuña and Chaudhry (1987), research results [18] (Figure 2.9).
