What is the minimum size of discharge for a tank used in sprinkler systems?

In sprinkler systems, the discharge capacity of a tank is crucial for ensuring that the system can deliver an adequate amount of water during a fire event. The minimum size of the discharge from a tank is typically determined by factors such as the required flow rate for the sprinkler system, the pressure requirements, and the tank's overall design.

Selecting a discharge size of 6 inches allows for appropriate water flow rates to support the demands of most sprinkler systems. It provides a balance between sufficient water supply and manageable pressure levels, enabling the system to operate effectively during emergencies. A larger discharge size could increase the flow rate significantly but might not be necessary for all designs, while a smaller size could limit water availability.

Understanding the significance of proper discharge sizing is crucial for sprinkler system design and compliance with local codes and standards.
