NFPA Reporting and Requirements

NFPA Requirements Using KYPipe, GoFlow, and Surge

Hydraulic Calculations

KYPipe, GoFlow, and Surge meet the formula requirements for calculations as described in

NFPA 13 – 22.4.2

NFPA 15 – 8.5

NFPA 16 – 7.4

Analysis scenarios and conditions outlined in these standards may be created within KYPipe and GoFlow.

Surge is limited to basic steady state analysis.  Surge specializes in unsteady flow analysis.  Therefore KYPipe or GoFlow is required to carry out some specific steady analysis scenarios such as Required Capacity, Remote Location, and ESFR.

 

NPFA 13 and 15 Reporting with KYPipe and GoFlow

A sprinkler system is developed within KYPipe or GoFlow.

Run an Analysis

Required Capacity analysis produces information required for NFPA reporting.

 

NFPA 13 and 15 Reporting Features

After analysis has been completed, open Summary/Supply Plot feature.

Both program interfaces are shown.
