Description
Return paper absorbed-water estimate after surface-water subtraction.
Studio material calculations distinguish gross stock, usable material, finished area and losses. A loss fraction can refer to material removed from the starting quantity or an extra allowance added to a requirement; these conventions produce different formulas and must remain explicit.
Return paper absorbed-water estimate after surface-water subtraction.
When to use this tool
Use Watercolor Class Paper Soak Mass Term when checking the stated studio material, shrinkage or usable-area convention.
How to use the tool and how it works
- Enter dryMass, wetMass, surfaceWaterEstimate. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read absorbedMass, absorptionPerDryMass. Use the output convention below.
Return paper absorbed-water estimate after surface-water subtraction. Require dryMass > 0, surface estimate >= 0 and wetMass >= dry+surface; absorbed = wet-dry-surface, ratio = absorbed/dry.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| dryMass | Dry Mass | Required. Finite number; strictly above 0. |
| wetMass | Wet Mass | Required. Finite number. |
| surfaceWaterEstimate | Surface Water Estimate | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| absorbedMass | Absorbed Mass | Required. Finite number. |
| absorptionPerDryMass | Absorption Per Dry Mass | Required. Finite number. |

}Limitations and assumptions
- This assumes compatible weighing and supplied water attribution; no conservation or paper-treatment suitability 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 measured material behavior, actual offcuts and process-specific trials to plan fabrication or firing; review classroom conditions with qualified staff.
