Answer :
In a fire sprinkler system, the minimum pressure is crucial for ensuring that the system operates effectively to control or extinguish fires. The standard minimum pressure required for a fire sprinkler system to operate effectively is generally 7 psi (pounds per square inch) for residential sprinklers and higher for commercial systems depending on the design criteria and specific use. However, in many industrial and commercial settings, a minimum of around 15 psi is required.
In the context of the given question, option c. 15 psi is the closest standard minimum pressure often used in fire sprinkler systems in various environments.
Here's why pressure is important:
Functionality: The pressure in the system ensures that when a sprinkler head activates, there is enough force behind the water to reach the fire effectively and cover the designated area.
Distribution: Adequate pressure helps in evenly distributing water and ensuring that all activated sprinkler heads receive sufficient water flow to suppress the fire.
Safety: In emergency situations, ensuring the fire sprinkler system operates as intended is vital for the safety of occupants and minimizing damage to the property.
Finally, it's important to mention that building codes and standards, such as those from the National Fire Protection Association (NFPA) in the United States, often determine specific pressure requirements based on building size, type, and occupation.
