What method can be fed off each specific pipe size in a sprinkler system?

The Pipe Schedule Method is a design approach used in sprinkler systems where the selection of pipe sizes is based on predetermined schedules established by the NFPA, specifically in NFPA 13. This method allows designers to select pipe sizes according to their flow rate requirements and the anticipated demand on the system without needing to perform detailed hydraulic calculations. Each specified pipe size in the Pipe Schedule Method provides guidelines on how much water can flow through it, making it practical for systems where the flow rates and pressures have already been evaluated and specified.

This method is particularly advantageous in simpler or smaller systems where detailed calculations may be unnecessary, allowing for quicker implementation of the installation. It is a straightforward way to ensure appropriate water supply and pressure are maintained based on the dimensions and configuration of the pipes used in the system.

Other methods, such as the Hydraulic Design Method, require more detailed calculations and analysis of the hydraulic characteristics of the system rather than relying on predefined schedules. Thus, the Pipe Schedule Method stands out for its ease of use when selecting pipe sizes for a sprinkler system.
