The formula works great for spreadsheets and programmable calculators! However, it is long and complicated enough that the industry standard process is still a great option.
You can ask the students that have just finished the Velocity Class, once you know the velocity calc process, it is a basic enough walkthrough. The tough part is getting the process down pat. The velocity process is simply a seven step process but what a process it is! Geeks like me enjoy the learning. It should be recognized that the above is my opinion as a member of the NFPA 13 Committee on Installation Criteria, and has not been processed as a formal interpretation in accordance with the NFPA Regulations Governing Committee Projects and should therefore not be considered, nor relied upon, as the official position of the NFSA nor the NFPA, nor any of their technical committees.
