Evaporation-adjusted level loss (mm)
Corrected drop=(tankInitial-tankFinal)-(controlInitial-controlFinal); litres=drop mm×area m².
Evaporation-adjusted volume loss (L)
Corrected drop=(tankInitial-tankFinal)-(controlInitial-controlFinal); litres=drop mm×area m².

Assumptions & limits
Assumptions & limits
- Comparable evaporation conditions assumed; signed result may be negative due to measurement error. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Comparable evaporation conditions assumed; signed result may be negative due to measurement error.
