💨 Safety Modeling (Choked Sonic Orifice kg/hr, Buoyant Dispersion Plume Distance)

Hydrogen Pipeline Leak Rate Calculator

Calculate sonic choked orifice gas release rates (kg/hr) and buoyant atmospheric dispersion plume safety zones for pressurized gaseous hydrogen pipelines and flanges under ISO/TR 15916 & CGA G-5.5: calculate high sonic velocity discharge ($>1,200 ext{ m/s}$), determine flammability envelope boundaries ($4.0% ext{ to }75.0% ext{ in air}$), and process safety profits.
