This assessment forms the foundation for the entire design process. A comprehensive hazard assessment ensures that the water spray system is tailored to the specific risks present in the protected area. A detailed hazard assessment is essential for determining the appropriate system design parameters. It ensures that the water spray system is tailored to the specific risks present in the protected area, providing optimal fire protection.

2. Hydraulic Calculations

Once you've assessed the hazards, it's time for hydraulic calculations. These calculations determine the water flow and pressure required to effectively control or extinguish a fire. Key factors to consider include:

• Nozzle discharge coefficient (K-factor): This value represents the nozzle's efficiency in discharging water.
• Friction losses in the piping network: Water flowing through pipes experiences friction, which reduces pressure. These losses must be accounted for in the calculations.
• Elevation changes: Changes in elevation can affect water pressure. The calculations must consider these variations.
• Required flow rate and pressure at each nozzle: Each nozzle must receive adequate water flow and pressure to deliver the desired spray pattern.

Hydraulic calculations are typically performed using specialized software that incorporates these factors to determine the optimal system design. Accurate hydraulic calculations are essential for ensuring that the water spray system can deliver the required water flow and pressure to control or extinguish a fire. These calculations must adhere to industry standards and regulations.

3. Component Selection

With the hydraulic calculations complete, you can now select the appropriate components for the system. This includes:

• Spray Nozzles: Choose nozzles that provide the required spray pattern and coverage area. Consider factors such as nozzle type, discharge rate, and spray angle.
• Piping: Select piping material that is compatible with the water supply and capable of withstanding the system's operating pressure. Common materials include steel, copper, and CPVC.
• Valves: Choose valves that are suitable for the system's flow rate and pressure requirements. Consider factors such as valve type, size, and material.
