Which of the following is true about deluge systems?

Deluge systems must be hydraulically calculated to ensure that they will provide adequate flow and pressure for firefighting when activated. This type of system is designed to discharge water over a wide area almost immediately upon activation since all the open sprinkler heads in a deluge system are connected to a single water supply line. Hydraulic calculations are critical in determining the necessary pipe sizes, water supply requirements, and effective distribution of water to ensure that the system can handle the potential volume needed for firefighting.

These calculations help prevent issues such as insufficient water supply or inadequate pressure, which could compromise the system's effectiveness during an emergency. Accurate hydraulic design plays a significant role in the overall reliability and efficiency of a deluge system, making this requirement essential for proper system performance.
