Assumptions & limits
Assumptions & limits
- Overall-liquid-vapour compositions. Returns Phase fraction from supplied equilibrium state. All coefficients and observations are user supplied; results describe only the stated mathematical model. 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. Overall light-component mole fraction z: minimum 0, maximum 1. Liquid mole fraction x: minimum 0, maximum 1. Vapour mole fraction y: minimum 0, maximum 1.
