## Description

Size hydronic pipes and get pump head (TDH) in seconds — steel, copper, PEX & CPVC. Darcy–Weisbach or Hazen–Williams. 100% offline, one-time purchase, no ads.

HydroSizer puts hydronic pipe sizing and pump head in your pocket. Size chilled- and hot-water pipes in seconds, then build the total dynamic head to select your pump — all offline, no subscription.

PIPE SIZING
• Enter flow (GPM, L/s, m³/h) plus a target head-loss rate or velocity
• Get the exact bore and the nearest nominal size for steel, copper, PEX or CPVC
• See actual velocity, head-loss rate and Reynolds number instantly
• Velocity guidance keeps you inside the design band

PUMP HEAD (TDH)
• Add pipe runs, fittings and equipment pressure drops
• Get total dynamic head with a clear breakdown: pipe, fittings, equipment, static
• Closed- and open-loop handling done right

ACCURATE ENGINE
• Darcy–Weisbach with Colebrook–White friction — or switch to Hazen–Williams
• Water properties by temperature; fittings via K-factor or equivalent length

BUILT FOR REAL WORK
• 100% offline — works anywhere, no signal needed
• One-time purchase — no ads, no subscription, no account, no data collected
• Fast, real-time results in a clean, modern interface
• US and metric units throughout

From the makers of AirCalc, DuctSizer and RefCalc — engineering tools that just work.
