Antifreeze Calculations

This webinar is on sprinkler systems utilizing antifreeze, based on NFPA 13 standards. This session will identify when sprinkler systems with antifreeze require hydraulic calculations using the Darcy-Weisbach formula and differentiate between the Hazen-Williams and Darcy-Weisbach formulas. Participants will also describe the critical components that must be accounted for friction loss in antifreeze systems to ensure effective fire protection.

At the completion of this seminar, you should be able to:

1. Identify the sprinkler systems that require hydraulic calculations using the Darcy-Weisbach formula.
2. Differentiate between the key differences of the Hazen-Williams and  Darcy-Weisbach formulas.
3. Describe the components that must be accounted for hydraulically in an antifreeze system.
