Which of the following is a function of hydraulic calculations in fire sprinkler systems?

Determining water supply needs is a crucial function of hydraulic calculations in fire sprinkler systems. These calculations assess the water demand required to effectively operate the sprinkler system and ensure that it can deliver the necessary water flow and pressure during a fire event. This involves calculating the amount of water needed at various points in the system, considering factors like the area being protected, the ceiling height, and any potential obstructions that could affect water distribution.

By accurately calculating the water supply needs, engineers and designers can ensure that the fire sprinkler system will be capable of suppressing a fire effectively, thereby enhancing safety for occupants and property. This is particularly vital for compliance with fire safety regulations and for the overall effectiveness of the fire protection strategy within a facility.

Other options do address important aspects of fire safety and system design, but they do not pertain directly to the role of hydraulic calculations, which specifically focus on the evaluation of water supply requirements for the operational effectiveness of the sprinkler system.
