What is the Maximum allaowed water velocity in fire sprinkler system?

The maximum allowed water velocity in a fire sprinkler system typically ranges between 20 to 30 feet per second (fps). This limit is set to minimize the risk of water hammer and damage to the piping system, as well as to ensure proper water distribution through the sprinklers. Specific regulations and standards, such as those from NFPA (National Fire Protection Association), may further dictate these parameters based on system design and application. Always consult the relevant codes and standards for the most accurate and applicable requirements.
