skill Proprietary (Paramus) — guidance only; execution performed by Paramus tools under their own license gating.
Retrieve and reconcile thermophysical properties (density, viscosity, heat capacity, phase behavior, vapor pressure) for a fluid or mixture across conditions using Paramus property engines (e.g. CoolProp/thermo), with unit handling and provenance.When to use: a user needs reliable physical properties at given T/P for design calculations.Multi-tool WORKFLOW with property-selection judgment.

Paramus — Thermophysical Property Lookup

Overview

Resolve a fluid/mixture, pick the right property model, and return properties at the requested conditions with units and provenance. The value is correct model selection + reconciliation, not a single lookup.

Guidance vs execution: properties come from tested Paramus property engines. Do not estimate properties with ad-hoc correlations.

When to Use

  • Physical properties at given T/P for design/sizing calculations
  • Phase behavior, vapor pressure, transport properties of a fluid/mixture Do not use for: full flowsheet simulation (hand off to the process workflow).

Workflow

Fluid / mixture + conditions (T, P, composition) + properties needed
  ↓ 1. Resolve components            → identifiers, mixture definition
  ↓ 2. Select property model         → equation of state / correlation appropriate to the fluid
  ↓ 3. Evaluate properties           → Paramus property engine
  ↓ 4. Unit & sanity checks          → consistent units, phase validity
  ↓ 5. Report                        → property table + model + provenance

Procedure

  1. Discover tools via search/get_schema ("fluid properties", "equation of state").
  2. Resolve components/mixture; confirm the composition basis.
  3. Select the property model appropriate to the fluid and conditions (state why).
  4. Evaluate the requested properties; capture engine + model version.
  5. Verify units and phase validity; report with provenance and any caveats.

Domain Judgment

  • The right EoS depends on the fluid (polar? near critical?) — state the choice and its limits.
  • Check the requested state is within the model's validity range; flag extrapolation.
  • Always return units; a property without units is a bug, not a result.

Fallbacks

  • Requested property/model unavailable → report; offer the nearest supported model with a caveat.
  • Endpoint unreachable → stop and report; no local correlations.
