A standard sprinkler operating at 100 psi will discharge how many gallons per minute?

A standard sprinkler head generally discharges water in a specified range based on its design and the pressure at which it operates. When a standard sprinkler operates at 100 psi, the flow rate is influenced by several factors including the orifice size of the sprinkler and the type of system it is part of. For most standard upright or pendant sprinkler heads designed for fire protection, the typical flow range at 100 psi is approximately 55 to 60 gallons per minute. This is consistent with what is recognized in fire protection engineering, where standard calculations and empirical data suggest that this is a common flow range for effective fire suppression.

Choosing the flow rate of 55-60 gallons per minute aligns with accepted firefighting practices, as this output is sufficient to support firefighting operations and suppress potential fire scenarios adequately. The correct flow rate, therefore, reflects the operational efficiency necessary to manage fire situations effectively while ensuring that the sprinkler system maintains optimum performance under specified pressure conditions.
