Assumptions & limits
Assumptions & limits
- Evaluate an explicitly supplied local linear density equation with user provenance. This is not TEOS-10 or EOS-80; users must supply and validate coefficients and their applicability range. Quantities are deterministic calculations from supplied observations and assumptions; no external data is fetched. Supported limits: Finite inputs only; numeric fields bounded as labelled. Lists and JSON records are limited to 256 entries unless a stricter tool bound is stated. No automatic design approval, legal conclusion, treatment recommendation or safety certification. Salinity (g/kg): minimum 0, maximum 50. Temperature (°C): minimum -2, maximum 40. Pressure (dbar): minimum 0, maximum 10000. Supplied linear equation [rho0,Sref,Tref,coefS,coefT,coefP]: minimum None, maximum 1000000000000.0.
