Fire Sprinklers 202 Introduction to Hydraulics: Overview of Hydraulic Calculations for Fire Sprinkler Systems

approx 90 minutes - 4 parts

CEUs = 0.15   /   CPDs = 1.5   (CEUs/CPDs are OPTIONAL)

This second 90-minute program of the three-part 200 series will continue to provide information to increase your understanding of what you should be able to determine from the plans and other submittal documents, and on the relevance of what is presented on those documents to the eventual approval, acceptance, or rejection on the part of your jurisdiction for the project under consideration on those plans.

Program 202 will focus on the review and analysis of the hydraulic calculations which are used to support the design of automatic sprinkler systems. This program is not intended to conduct an in-depth explanation of the science of hydraulics, which is not the focus of this series or program. For an in-depth course on learning hydraulic calculations, go to the Fire Sprinkler eCampus.

On completion of this program you will be able to:

  • Interpret the limitations on the use of pipe schedules in sprinkler system design
  • Recognize the information required by NFPA 13 to be on the cover sheet of submitted hydraulic calculations supporting sprinkler system design
  • Identify the location of all reference points on the sprinkler system drawings
  • Explain the use of equivalent K-factor in sprinkler system hydraulic calculations
  • Perform node analysis of fire sprinkler system hydraulic calculations to evaluate compliance with requirements for each flowing sprinkler
  • Calculate the area of coverage for each sprinkler using the S´L method from NFPA 13
  • Discuss the Hazen-Williams formula and the Darcy-Weisbach formula used in NFPA 13 calculations
  • Complete a 1.85 exponential (hydraulic) graph paper in plotting water demand in relation to supply
