What term refers to sprinkler performance metrics for water flow?

• A. Discharge characteristics
• B. Test Results
• C. Listing limitations
• D. Nominal K-5.6

Answer: (A)

Discharge characteristics describe sprinkler performance metrics for water flow. They capture how much water a sprinkler delivers at a given inlet pressure, including flow rate (gpm), the pressure requirements, and the resulting spray pattern and throw. This set of data is what engineers use for hydraulic calculations and to compare how different sprinkler models perform under pressure. The K-factor (for example, nominal K-5.6) is part of this relationship, since discharge is often expressed with Q = K√P, but the general term for these performance metrics is discharge characteristics. Test results may show data, but they’re not the standard term for the overall performance data; listing limitations relate to approvals, and a specific nominal K value is just one data point within the discharge characteristics.
