Steam Tables Lookup

// SATURATION | SUPERHEATED | REVERSE STATE LOOKUPS

State Lookup

Interpolates against vendored LearnChemE steam table CSVs. All math runs in SI units; display units are converted at the boundary.

Lookup mode Units Pressure units Example

Inputs

Load tables and enter a state to compute properties.

Interpolation details will appear after a lookup.

Phase Context

Compute a state to see its phase region and saturation distance.

Charts

Charts use the saturated CSV rows as context and overlay the current state plus pinned comparison states when they have plottable coordinates.

Compute a state to draw saturation context charts.

State Comparison

Pin State A and State B to compare property deltas.

Internal Consistency Tests

The test runner checks parser counts, exact CSV grid points, midpoint interpolation, reverse round trips, table-gap handling, and unit round trips.

Run tests to compare interpolation paths against the vendored CSV rows.

Data Source

CSV data is vendored from LearnChemE Steam Tables, authored by Neil Hendren at CU Boulder. The CSV metadata carries an MIT-style permissive notice retained in each source data file; broader LearnChemE pages identify LearnChemE work as CC BY-SA 4.0.
