Drained retained water (mL)
(Drained−dry baseline)/water density.
Observed container water fraction (mL/mL)
Retained water/substrate volume.
Drainage water (mL)
(Saturated−drained)/water density.

Assumptions & limits
Assumptions & limits
- Saturated-drained-dry weights, volume. Returns Observed retained water and mass balance. 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. Saturated container mass (g): minimum 1e-12, maximum 1000000000000.0. Drained container mass (g): minimum 1e-12, maximum 1000000000000.0. Dry container-plus-substrate baseline (g): minimum 1e-12, maximum 1000000000000.0. Substrate volume (mL): minimum 1e-12, maximum 1000000000000.0. Water density (g/mL): minimum 1e-12, maximum 1000000000000.0.
