Storage Sprinkler Hydraulics

There are a variety of sprinkler technologies on the market to protect modern storage arrangements. This presentation reviews the basic discharge requirements for CMDA, CMSA, and ESFR sprinklers in NFPA 13. In addition, it explores new concepts introduced for the 2025 edition of NFPA 13 and alternate design approaches available from other resources.

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

1. Identify the discharge requirements for CMDA, CMSA, and ESFR sprinklers
2. Identify alternate design schemes outside of NFPA 13
3. Estimate the total sprinkler demand for each sprinkler type
4. Identify specific calculation requirements for storage sprinklers
5. Apply new discharge requirements for supplemental sprinklers
