Sprinkler Hydraulics
Full tree, looped, and gridded system analysis per AS2118. K-factor discharge, Hazen-Williams, and automatic remote area selection.
Design, verify, and document fire sprinkler and hydrant systems to AS2118 standards — with the precision and speed your authority submissions demand.
Engineered for NSW · VIC · QLD · WA · SA · TAS · ACT · NT
Built from the ground up for Australian fire protection engineers. Purpose-designed for AS2118.
Full tree, looped, and gridded system analysis per AS2118. K-factor discharge, Hazen-Williams, and automatic remote area selection.
Newton-Raphson primary solver with Hardy Cross fallback. Handles unlimited looped systems. Converges to 0.001 L/min.
Pump curves, gravity tanks, and town mains. Automatic supply-vs-demand comparison with clear pass/fail results.
Calculations to AS2419 and AS2441. Combined sprinkler-hydrant systems and simultaneous outlet selection.
Company accounts with domain enforcement. Threaded project comments and role-based access for engineering teams.
Authority-ready reports in one click. Node pressures, pipe schedules, and supply curves formatted for DA lodgement.
Every node, every pipe, every iteration. No black boxes — just the maths your authority reviewer expects to see.
Every node stores type, elevation and operating status. Active discharge nodes drive the remote-area iteration — visible at a glance.
DN, internal bore, C-factor, fittings, and equivalent length. The solver uses every field — no hidden defaults or black-box adjustments.
The same diagram that solves the system appears in your PDF — nodes, pressures, flows, and pipe schedule, ready for authority review.
Real-time calculation results, pipe-by-pipe breakdowns, and team activity—structured exactly how fire protection engineers work in the field.
Every formula and input is visible and editable.
Instant feedback on velocity and pressure limits.
One-click reports formatted for Australian authorities.
Eliminate security risks with One-Time Passcodes. Enter your work email, receive a secure link, and start calculating in seconds.

Eliminate fragmented spreadsheets and email chains. Review calculations, flag velocity issues, and approve supply margins in a unified environment designed for Australian engineering standards.
Pipe P-04 is 2.6 m/s on the 40mm branch. Getting close to 3 m/s limit. Recommend resizing.
Updated to 50mm — velocity drops to 2.1 m/s. Recalculation still passes.
Supply margin is +0.35 bar — confirm flow test data is current.
Absolutely. Our solver is specifically engineered to follow AS2118, AS2419, and NFPA methodology, ensuring all hydraulic reports are ready for Australian DA and authority submissions.
No. FireCalc Pro is a cloud-native platform. You can access your projects, calculations, and team workspace from any browser, whether you're in the office or on-site.
Yes. Our Pro and Enterprise plans feature shared company libraries, threaded project comments, and role-based access control (Owner, Admin, and Engineer).
We utilize a Newton-Raphson primary solver for looped and gridded systems, converging to 0.001 L/min tolerance, meeting the rigorous standards of modern fire engineering.
