What determines the K-factor in sprinkler systems?

• A. The flow rate of water
• B. The pressure applied to the system
• C. The density of smoke particles
• D. The type of fire suppression agent used

Answer: (A)

The K-factor in sprinkler systems is a critical parameter that indicates how much water a sprinkler can discharge at a given pressure. It is defined based on the flow rate of water that flows through the sprinkler head. Specifically, the K-factor is calculated using the formula that relates the flow rate (in gallons per minute) to the pressure (in pounds per square inch) at which water is discharged from the sprinkler. This relationship allows for the design and selection of sprinklers that will provide the appropriate amount of water in case of a fire, ensuring effective suppression according to the needs of the area being protected. Understanding the K-factor is essential for engineers and fire protection professionals because it helps in the proper design of fire protection systems, ensuring that they can adequately respond to varying fire scenarios while maintaining safety and compliance with fire codes. The K-factor does not relate to smoke particle density or the type of fire suppression agent, which are separate considerations in fire investigation and management.
