Unformatted text preview: period of water-hammer was decreased. (g) The friction factor was increased to 0.05. It could be observed by TranSAM that the water-hammer pressure was decreased, and the period of water-hammer was not changed. (h) The irregular pattern in the pressure history was observed by TranSAM because of the superposition of the reflected wave and vapour cavitation in the model. Also, as the waves were traveling and the phases were changing. Thus, the waves were interacted together Therefore, the irregular pattern happened in the pressure history. Using Joukowsky relation is suitable for design of pipeline because it could prevent the breakage of the closed pipes....
