Flowforge: Fire Sprinkler Kit

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