Hydraulic Analysis for water-based fire protection systems verifies that the system delivers adequate flow, pressure, and performance in accordance with international fire protection standards and Korean fire safety regulations. This critical design validation applies to all water-based suppression systems, including sprinkler, water spray, deluge, monitor, and foam-water systems.
The analysis confirms hydraulic adequacy by ensuring the system provides required flow and discharge characteristics to all demand points, including the most hydraulically remote location, while maintaining necessary pressure under all design operating conditions with stable and uniform water distribution. Using specialized hydraulic modeling software such as PIPENET (Spray/Sprinkler Module), the analysis encompasses the complete piping network from pump discharge to terminal devices. The modeling evaluates friction losses using established methods such as Hazen–Williams equations, comprehensively simulating pipes, fittings, valves, nozzles, and discharge components under real operating conditions.
Key verification items include residual pressure at critical discharge points, consistent water distribution ensuring adequate coverage and density, flow velocity maintained within acceptable limits, and fire pump performance validation for the most demanding scenarios. This analysis validates that the water-based fire protection system provides reliable, effective, and code-compliant suppression performance for industrial facilities, energy plants, and critical infrastructure under all designated design conditions.
