Calculation method

Calculation method

Initial wet-basis moisture fraction

(wet−dry)/wet.

Initial dry-basis moisture ratio

(wet−dry)/dry.

Target product mass (kg)

Dry solids/(1−target wet-basis moisture).

Water to remove (kg)

Initial wet mass−target mass; negative means water addition.

Assumptions & limits

Assumptions & limits

  • Wet-dry masses, target moisture convention. Returns Wet-basis and dry-basis quantities. 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. Wet sample mass (kg): minimum 1e-12, maximum 1000000000000.0. Dry solids mass (kg): minimum 1e-12, maximum 1000000000000.0. Target wet-basis moisture fraction: minimum 0, maximum 0.999999.
