Description
Return dry-basis moisture driving force relative to equilibrium.
A process stream can be described on mass, mole, phase or solvent bases, which are not interchangeable. Lever rules, partition factors and operating-line terms assume compatible composition definitions and an appropriate physical model; a local balance does not determine equilibrium properties or a complete separation design.
Return dry-basis moisture driving force relative to equilibrium.
When to use this tool
Use Drying Moisture Equilibrium Driving Force when checking the stated stream composition, phase or separation-model term.
How to use the tool and how it works
- Enter moistureDryBasis, equilibriumDryBasis, criticalDryBasis. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read freeMoisture, freeMoistureRatio. Use the output convention below.
Return dry-basis moisture driving force relative to equilibrium. Require nonnegative moisture/equilibrium and critical > equilibrium; freeMoisture = moisture-equilibrium, freeMoistureRatio divides by critical-equilibrium.1

}Limitations and assumptions
- Signed free moisture and ratios beyond [0,1] are retained; no drying rate, equilibrium model or safe drying condition is determined.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified equilibrium and material-property data on consistent bases and solve the complete process model for actual separation or equipment decisions.
