Air release refers to the process of expelling trapped air from a system, such as a pipeline or a container. This is important in various applications, including water distribution systems, where air pockets can cause pressure fluctuations and reduce efficiency. By allowing air to escape, the system can operate smoothly and maintain optimal performance. In engineering, devices like air release valves are used to facilitate this process. These valves automatically open to release air when pressure builds up, ensuring that liquids can flow freely. Proper air release helps prevent issues like water hammer, which can damage pipes and equipment.
