{"jsonrpc":"2.0","id":1,"method":"tools/list"}nist_fluid_properties — Density, specific volume, internal energy, enthalpy, entropy, Cv, Cp, speed of sound, Joule-Thomson coefficient, viscosity, thermal conductivity and phase (liquid/vapor/supercritical) for one of NIST's ~76 reference fluids (water, nitrogen, oxygen, argon, CO2, hydrocarbons, refrigerants...) at a given temperature and pressure. Every value carries its unit. Call nist_fluid_list first if unsure a fluid is covered.nist_fluid_saturation — Liquid/vapor saturation (phase-boundary) properties for one of NIST's ~76 reference fluids — give EITHER a saturation temperature (returns the matching saturation pressure, e.g. boiling point at 1 atm) OR a saturation pressure (returns the matching saturation temperature), plus density, enthalpy, entropy, viscosity, thermal conductivity and surface tension on both the liquid and vapor side of the boundary. Do not pass both temperature and pressure.nist_fluid_list — List the ~76 fluids NIST's Chemistry WebBook carries full thermophysical property surfaces for (water, nitrogen, oxygen, argon, CO2, light hydrocarbons, refrigerants R11-RC318, and a few industrial gases). Optionally filter by a substring of the name or refrigerant code.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
