SimuPipe: Simulate pipe flow & pressure drop in your browser

Hi Product Hunt! 👋 I built SimuPipe because pipe network simulation has been stuck in expensive, install-only desktop software for decades. As an engineer I wanted something I could just open in a browser, sketch a network, and get real hydraulics back in seconds — without a four-figure license. SimuPipe runs steady-state simulations for both liquids and gases: pressure drop, flow distribution, velocities, control valves (IEC 60534 Cv/Kv), pumps and orifice plates across 38 fluids. The entire free tier runs in your browser — nothing to install. It's aimed at engineers who've outgrown spreadsheets but don't want EPANET's learning curve or AFT/Pipe-Flo's price tag. I'd love your feedback — especially from anyone doing piping, HVAC, process or hydraulics work. What would make this genuinely useful in your day-to-day?
