What is the Design Discharge?

Explanation:
The Design Discharge is the flow rate the sprinkler system must deliver under the design-fire conditions. It is the target water flow used in hydraulic calculations to verify that the system can meet the required design density over the design area, and to size the pump, pipes, and water supply accordingly. In NFPA 13R, this discharge rate represents the amount of water the system is expected to deliver to control or suppress a fire at the design point. This concept is not about a fuel-fired heating unit, a specific dwelling unit type, or a compartment; it specifically refers to the flow the system is designed to discharge under design conditions.
