## Description

Flowforge puts a sprinkler fitter&#39;s daily math and reference tables in one fast, offline app. Built by a life-safety trades background, not a software company guessing at what the field needs.<br><br>HYDRAULICS<br>• K-Factor Flow — Q = K√P, solve for flow, pressure, or K<br>• Friction Loss — Hazen-Williams with real Sch 40 / Sch 10 / copper / CPVC pipe IDs<br>• Flow Test Analysis — project available gpm at 20 psi from static, residual, and test flow (Pro)<br>• Pitot Flow — outlet flow from pitot pressure and coefficient<br>• Pipe Volume — gallons per run with a running system total (Pro)<br>• Water Velocity and Elevation ↔ Pressure converters<br><br>SPACING &amp; LAYOUT<br>• Sprinkler Spacing — max coverage and spacing by hazard and construction<br>• Hanger Spacing — steel, lightwall, copper, and CPVC tables<br>• Trapeze Sizing — section modulus from span and load, with the member picked for you (Pro)<br>• Obstructions — beam rule and three-times rule calculators (Pro)<br>• Deflector Position — distance below ceiling and storage clearance checks (Pro)<br><br>SYSTEMS &amp; TESTING (Pro)<br>• Dry System Air — air pressure from supply static and valve ratio<br>• Pipe Pitch — drop over run for drainage<br>• Fire Pump Check — churn / 100% / 150% test points against the rated curve<br>• Standpipe Demand — Class I–III flow and pressure<br>• Main Drain Test — compare against baseline with the 10% rule<br>• Hydrostatic Test — required pressure and duration<br><br>REFERENCE<br>• K-Factor Chart — orifice sizes, threads, % of K5.6<br>• Temperature Ratings — classifications with glass bulb colors and frame colors<br>• NFPA 25 ITM — searchable inspection, testing, and maintenance frequencies (Pro)<br>• Pipe Data — OD, ID, gallons per foot, water-filled weight<br>• Fitting Equivalent Lengths — C=120 table with C-factor adjustments (Pro)<br>• Hazard Classifications, System Types, and every formula on one card<br><br>FREE VS PRO<br>12 tools are free forever, with a small banner ad. One inexpensive one-time purchase unlocks all 26 tools and removes ads permanently. No subscription. No account. No sign-in.<br><br>BUILT FOR THE FIELD<br>• Works 100% offline — riser rooms and basements have no bars<br>• Dark interface built for dim mechanical rooms<br>• Monospace results you can read at arm&#39;s length<br><br>Flowforge is a field reference, not an engineering authority. Always verify results against the adopted NFPA edition, product listings, approved drawings, and your AHJ.<br><br>From TapForge Studios — the maker of Pipeforge, Voltbox, Airforge, and Fireforge.
