K factors for standard coverage sprinklers range from ___________.

• A. A. 1.4 to 14
• B. B. 1.4 to 28
• C. C. 2.8 to 16.8
• D. D. 16.8 to 28

Answer: (A)

In fire sprinkler systems, the K factor is a critical measurement that determines the flow rate of water through the sprinkler head for a given pressure. This factor is essential for ensuring that the appropriate amount of water is delivered to effectively control or extinguish a fire. For standard coverage sprinklers, the K factors typically range from 1.4 to 14. This range is derived from standards established in the National Fire Protection Association (NFPA) guidelines, which provide specific K factor values that correspond to the water discharge characteristics of different types of sprinkler heads. Sprinklers with a K factor of 1.4 are generally used for light hazard applications, whereas those with a higher K factor approach 14 are suited for more intense fire hazards, allowing for greater water discharge. By correctly identifying and using the K factor, contractors can ensure their sprinkler systems are properly designed to meet the demands of specific fire protection scenarios. The other ranges provided in the options either exceed the typical values or fall short, making the specified range of 1.4 to 14 the most accurate for standard coverage sprinklers. This understanding is crucial for those involved in the design, installation, and maintenance of fire sprinkler systems.
