About

Hydrant Flow Test Calculator

This tool simplifies hydrant flow testing by calculating total GPM from pitot pressures. It allows for outlet settings, flow extrapolation with a Supply vs Demand curve, and plotting demand points for PASS/FAIL results. Save test data with location and project details for future reference.

Highlights
  • Calculate total GPM from pitot pressures
  • Configure outlet diameter and hydrant coefficients
  • Extrapolate flow with Supply vs Demand curve
  • Plot demand points for PASS/FAIL analysis
  • Save test results with date, time, and project info
  • Log hydrant locations via GPS
  • Review saved test history

Hydrant Flow Test Calculator is a field-friendly calculation and reporting tool for fire protection professionals, engineers, inspectors, contractors, and AHJs who need to evaluate and document hydrant flow test results. The app helps calculate hydrant flow from field readings, compare available water supply against system demand, estimate downstream friction loss, and export professional PDF reports. Key features: • Calculate hydrant flow using static pressure, residual pressure, pitot pressure, outlet diameter, and discharge coefficients • Calculate total test flow and flow at a target residual pressure • Compare available supply against system or pump demand • Review demand pass/fail results with available pressure and safety cushion • View Supply vs Demand graph with demand point legend • Save completed test records to History • Add project information including associate, project number, project location, test hydrant tag, and flow hydrant tag • Optionally capture test hydrant and flow hydrant coordinates • Attach an image to a saved test record • Export PDF reports with project details, test summary, demand results, graph, location details, friction loss results, and attachment • Estimate friction loss using pipe product, nominal pipe size, inside diameter, pipe length, C-factor, elevation, minor loss, and device/backflow loss • Supports US and SI flow display The Friction Loss tool includes pipe product and nominal pipe size selection with automatic inside diameter lookup. Elevation guidance helps users enter positive values for uphill and negative values for downhill conditions. Hydrant Flow Test Calculator is designed to make field calculations faster, improve documentation consistency, and help organize hydrant flow test information in one place. This app is intended as a calculation and documentation aid. Users are responsible for verifying all inputs, assumptions, calculations, and results according to applicable codes, standards, project requirements, and professional judgment.
