pared by Field Tests results. Results indicates that at water hammer condition of (110M
transient pressure), in the vicinity of pump station, leakage has been happened. Hence,
the leakages of Transmission Line can occur nearby water treatment plant. Also water
transmission flow decreased from 3000 (l/s) to 2500 (l/s).
Therefore, it is always a good idea to check extreme transient pressures for any
system with large changes in elevation, long pipelines with large diameters (i.e., mass
of water), and initial (e.g., steady-state) velocities in excess of 1 (m/s). In some cases,
hydraulic transient forces can result in cracks or breaks, even with low steady-state
velocities (Table 4.3-4.7).
