PaperLab Equation Dimensional Audit
When to Use
USE WHEN: reviewing equations, formula notation, unit consistency, or repeated technical correlations in an engineering textbook.
Pair with:
paperlab_scientific_traceability_auditfor equation provenance,neqsim_in_writingfor implementation links,paperlab_standards_clause_traceabilityfor standards-based formulas.
Audit Dimensions
| Dimension | Check |
|---|---|
| symbol | defined near first use or in nomenclature |
| unit | stated and dimensionally plausible |
| source | citation, standard, derivation, or implementation link |
| assumption | valid range or simplification stated |
| duplicate | repeated formula uses same notation or explains differences |
| implementation | NeqSim method/test link when used computationally |
Workflow
- Extract display equations delimited by
$$...$$and inline formulas using$...$when they contain engineering symbols. - Normalize symbols and compare against
nomenclature.yaml. - Check units and dimensions where possible.
- Detect conflicting definitions such as
qfor heat duty and volumetric flow in the same chapter without clarification. - Detect formula variants that need an assumptions note.
- Recommend nomenclature additions and local text fixes.
Output Pattern
## Equation Audit: <chapter>
- Status: ready | minor-revision | major-revision | blocked
- Undefined symbols:
- <symbol and equation context>
- Unit issues:
- <quantity and suspected issue>
- Formula variants:
- <formula family and recommended distinction>
- Recommended next edit: <one concrete action>
Safety Rules
- Do not declare an equation wrong from notation alone.
- Treat approximate teaching equations as acceptable when assumptions are clear.
- Never invent standards clauses or citations for equations.
