Hydraulic Calculations for Fire Sprinkler Systems

Hydraulic calculation software not only saves time but also helps prevent costly errors. In this video, we introduce free educational online tools that make performing hydraulic calculations easier and more reliable. We’ll walk through a more complex example than the one in our step by step video, showing how these tools can be used to determine friction loss, calculate equivalent K factors, and find equivalent lengths, all while streamlining the design process. 🔹 𝐓𝐨𝐩𝐢𝐜𝐬 𝐂𝐨𝐯𝐞𝐫𝐞𝐝: ✅ Defining Nodes & Elevations ✅ Understanding the K Factor ✅ Nominal Pipe Size & Internal Diameter ✅ Equivalent Length of Fittings & Valves ✅ C Factor & Hazen Williams Formula ✅ Water Supply & System Curves ✅ Evaluating Water Supply Capability ✅ Safety Margin (psi & %) 𝐑𝐞𝐜𝐨𝐦𝐦𝐞𝐧𝐝𝐞𝐝 𝐏𝐫𝐞𝐫𝐞𝐪𝐮𝐢𝐬𝐢𝐭𝐞 𝐕𝐢𝐝𝐞𝐨𝐬: https://www.youtube.com/watch?v=W7Iowc12Z94 https://www.youtube.com/watch?v=MLzKGlqLcg0 https://www.youtube.com/watch?v=3y7tnLr86cE https://www.youtube.com/watch?v=GV4ujJbIlSw https://www.youtube.com/watch?v=0mrerqLDnxw https://www.youtube.com/watch?v=M0kZuunL4Ds https://www.youtube.com/watch?v=MBErDhmlaPo 𝐑𝐞𝐥𝐚𝐭𝐞𝐝 𝐕𝐢𝐝𝐞𝐨: https://youtu.be/K5ftiomPZvE #HydraulicCalculations #FireProtection #NFPA13 #FreeSoftware #SprinklerDesign #hesamtavoosi 00:00 Introduction to NSVSOFT Online Tools 00:41 Key Features & Tool Capabilities 01:31 Example Project: Textile Manufacturing Occupancy 03:15 Sprinkler Layout & Tree Piping Configuration 03:51 Initial Pipe Size Selection Strategy 05:08 Defining Nodes for Hydraulic Calculations 05:47 Establishing Node Elevations & Reference Planes 06:42 Starting the Hydraulic Calculation: Project Data 07:46 Section 1 (Nodes 101-102): Branch Line Setup 10:04 Sections 2 & 3: Adjusting Pipe Sizes 10:24 Section 4 (Nodes 104-1): Riser Nipple & Fittings 11:27 Section 5: Cross Main Calculations 11:43 Section 6 & 7: Equivalent K-Factor Method 13:02 Section 8: Calculating Single Sprinklers on Branch Lines 14:25 Section 9: Riser Devices & Manufacturers' Data 15:05 Final Section: Underground Piping & Backflow Preventers 16:25 Adjusting Equivalent Length for Different Pipe Types 17:32 Water Supply Analysis: Flow Test Data 18:05 Graphical Method vs. Mathematical Method 20:37 Calculating Safety Margins & Conclusion
