The "K-factor" is a critical parameter in the design and functioning of sprinkler systems, specifically related to the flow characteristics of the sprinkler heads. It is defined as the relationship between the pressure of the water and the volume of water flowing through the sprinkler head. By using the K-factor, one can calculate the discharge rate of water based on the pressure applied to the sprinkler.

When you apply a specific pressure at the sprinkler head, the K-factor helps to determine how much water will be discharged. A higher K-factor indicates a larger flow rate for a given pressure, while a lower K-factor indicates a smaller flow rate. This relationship is crucial in ensuring that the design of the sprinkler system can effectively control a fire by providing the right amount of water at the right pressure.

In this context, the significance of the K-factor is paramount as it directly influences the performance of the system, ensuring adequate water flow for fire suppression while optimizing water usage. Understanding the K-factor allows for proper selection of sprinkler heads and sizing of the system, making it essential knowledge for anyone involved in the design and installation of fire sprinkler systems.
