Welcome to CaidentCalc
CaidentCalc is a desktop application for hydraulic calculation of fire-sprinkler systems. You describe the system — water supply, nodes, pipe segments, and the sprinklers that flow — and CaidentCalc solves the pressures and flows throughout the system, grades every calculation area Pass or Fail against your water supply, and produces a submittal-ready PDF report with a cover sheet and water-supply curve.
Advisory
CaidentCalc is intended to support professional fire protection design. Calculation inputs and results should be reviewed by a qualified fire protection professional before use in permit, construction, or other formal documents. Caident assumes no liability for calculations relied upon without appropriate professional review.
What CaidentCalc does
- System entry built for speed — spreadsheet-style tables for nodes, pipe segments, pumps, and fixed losses, with keyboard-first navigation and dimension-style input (
5'2.4"works exactly as typed). - Server-side solving — the calculation runs on Caident's servers, so results are identical everywhere.
- Full results — per-area pass/fail with safety margins, node pressures and discharges, a segment-by-segment friction analysis, and the water-supply curve.
- Professional PDF reports — a configurable cover sheet (company profiles, occupancy-based design criteria, base-of-riser data), one PDF per calculation area or a single combined document.
- Pipe-table management — view, create, and edit
.cpipefitting tables, or import HASS.piptables. - Third-party import (beta) — read existing calculations out of HASS, AutoSPRINK, and HydraCAD report PDFs (and HASS
.sdffiles) and map their pipes into your tables.
Three ways a project starts
- Open or create a
.ccalcproject — chapter 3 and chapter 14. - Import a third-party calculation — a HASS/AutoSPRINK/HydraCAD report PDF becomes an editable CaidentCalc project (chapter 11).
- Receive it from Caident Design — the companion CAD app sends its piping model straight into CaidentCalc over a local link (chapter 12).
Who this manual is for
Fire-sprinkler designers and engineers who know hydraulic calculation — K-factors, C values, flow tests — and want to know how this particular tool works.
Conventions
- Keys look like this: press Ctrl+T to calculate.
- Menu paths use arrows: File → Export PDF.
- On-screen labels are bold, exactly as they appear.
| Term | Meaning |
|---|---|
| Node | A point in the network: a sprinkler, a junction, or the supply source. |
| Segment | What connects two nodes: a pipe (with material, diameter, length, fittings), a pump, or a fixed loss. |
| Calculation area | A named set of flowing sprinklers with K-factors and minimum flows — each area is solved and graded separately. |
| Pipe table | The catalogue of materials, diameters, C values, and fitting equivalent lengths the solver reads from (.cpipe). |
