Great straight forward article explaining K-factor of sprinkler heads.
𝐔𝐧𝐝𝐞𝐫𝐬𝐭𝐚𝐧𝐝𝐢𝐧𝐠 𝐭𝐡𝐞 𝐊-𝐅𝐚𝐜𝐭𝐨𝐫 𝐢𝐧 𝐅𝐢𝐫𝐞 𝐒𝐩𝐫𝐢𝐧𝐤𝐥𝐞𝐫 𝐇𝐞𝐚𝐝𝐬: In the world of fire protection, the K-factor is a crucial element in the design and functionally sprinklers systems. 𝐒𝐨, 𝐰𝐡𝐚𝐭 𝐢𝐬 𝐭𝐡𝐞 𝐊-𝐟𝐚𝐜𝐭𝐨𝐫? The K-Factor, or (Discharge coefficient), essentially measures the flow rate of water through a sprinkler head at a given pressure. 𝐊=𝐐/(√𝐏) Where: K: The K-Factor Q: Flow rate, gpm (gallons per minute) P: Pressure, psi (pounds per square inch) A higher K-Factor means a larger orifice, allowing more water to flow through, which suitable for high hazards areas. Conversely, a lower K-Factor restricts the flow, means a smaller orifice, allowing less water to flow through, which suitable for areas with lower fire risks. 𝐖𝐡𝐚𝐭 𝐦𝐚𝐤𝐞𝐬 𝐭𝐡𝐞 𝐊-𝐅𝐚𝐜𝐭𝐨𝐫 𝐒𝐢𝐠𝐧𝐢𝐟𝐢𝐜𝐚𝐧𝐭? 1. Precision in design: To ensure that the sprinkler system deliver the right amount of water to control or extinguish a fire. 2. Efficiency: Helps in optimizing the hydraulic calculations, reducing unnecessary pressure loss. 𝐕𝐚𝐥𝐮𝐞𝐬 𝐨𝐟 𝐊-𝐅𝐚𝐜𝐭𝐨𝐫: The K-Factor is depending on the type and application of sprinkler, here are some common K-Factor values and some common applications: - 𝐊𝟐.𝟖: Used in residential applications where lower water flow is sufficient. - 𝐊𝟓.𝟔: The most common K-Factor, typically used in light hazard occupancies like offices and schools - 𝐊𝟖.𝟎: Used in ordinary hazard occupancies where a higher flow rate is needed. - 𝐊𝟏𝟏.𝟐: Common in high-hazard areas, such as warehouses, where a significant amount of water is required to control a fire. - 𝐊𝟏𝟒.𝟎 and above: Used in special applications like a storage facilities with high-piled storage or areas requiring Early Suppression Fast Response (ESFR) sprinklers.
