Gasnetics

Gasnetics is a web app for designing and verifying gas distribution networks — natural gas, LPG, biomethane and hydrogen blends. Draw the network on a real map, assign demands and pressures, and calculate flows, pressures and velocities with the general flow equation (Colebrook-White friction). The app checks velocity and minimum-pressure limits per pipeline class, sizes diameters automatically from commercial catalogues (PE, steel), imports existing networks from Shapefile, GeoJSON and CSV, and generates a complete PDF calculation report: network plan, methodology, full results, pressure profile and bill of quantities. Every published result is validated against hand-worked canonical cases. Runs in the browser, nothing to install. Currently in free beta.
