Abstract

 Background and Objective: One of the most effective methods of coping with Leakage in Water Distribution Networks is pressure management. Therefore, a proper understanding of Leakage behavior and its relationship with pressure variations can play a significant role in water loss control. The use of high-density polyethylene (HDPE) pipes has increased in recent years in Water Distribution Networks so that in some rural area and small cities, these pipes have been utilized only. The aim of this study is to investigate the Leakage behavior of Orifices in HDPE pipes. Method: In the present study, the Leakage behavior of polyethylene pipes has been investigated numerically and experimentally. In this study, the effect of temperature as one of the main factors on Leakage behavior has been considered. Findings: The results showed that the Torricelli's classic relationship for the Orifices can be used and the amount of Leakage exponent for the Orifices is approximately 0. 5. This study shows that the discharge coefficient of the outflow from the Orifices is dependent on some parameters such as Reynolds number, the thickness of pipe wall, Orifice diameter, surrounding environment and Orifice deformation. Discussion and Conclusion: The assumption of no deformation for the Orifices in HDPE pipes with increasing pressure, particularly at high temperatures, is not necessary true. The symmetry state of the Orifices in low-elastic pipes is removed with the pressure increase, due to the distribution of stress at the opening and also the effect of the Poisson coefficient, thereby reducing the discharge coefficient.
