Water hammer in pumped discharge line poses challenges, leading to pressure surges and potential damage. Air chambers effectively mitigate these challenges, yet their construction involves significant costs. This study focuses on water hammer issues in a pumped discharge line, with a specific emphasis on air chambers as protective devices. The impacts of air chamber parameters such as initial air volume, orifice diameter, and minor loss coefficient on water hammer effects are investigated. Numerical analyses considering various air chamber parameters have been performed using a transient analysis software, OpenFlows Hammer. The study concludes with a cost minimization approach, considering both the effectiveness of protection and cost factors. It is possible to select the most effective air chamber volume which provides effective protection against water hammer while minimizing costs, utilizing the cost minimization approach in the study.
