Calculation method

Calculation method

Blended salt mass fraction

Total salt=sum(solutionMass×saltFraction); divide by total solution mass.

Total salt mass (kg)

Total salt=sum(solutionMass×saltFraction); divide by total solution mass.

Total solution mass (kg)

Total salt=sum(solutionMass×saltFraction); divide by total solution mass.

Assumptions & limits

Assumptions & limits

  • Mass fraction, not practical salinity units; no livestock target. 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. Mass fraction, not practical salinity units; no livestock target.
