Expected final volume (L)
Initial+sum additions−sum removals; negative balance rejected.
Unexplained observed-minus-expected volume (L)
Observed final−arithmetic expected final; negative means unaccounted loss.

Assumptions & limits
Assumptions & limits
- Initial volume, additions, removals, observed level. Returns Water balance and unexplained difference. 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. Initial reservoir volume (L): minimum 0, maximum 1000000000000.0. Added water volumes (L): minimum 0, maximum 1000000000000.0. Known removed volumes (L): minimum 0, maximum 1000000000000.0. Observed final volume (L): minimum 0, maximum 1000000000000.0.
