Description
Return solidVolume = measuredVolume*(1-voidFraction) and estimatedMass = solidVolume*solidDensity.
Mass-based environmental quantities depend on their basis: gross versus tare-corrected mass, wet versus dry solids, or material versus void volume. A ratio or density conversion is meaningful only when those bases and units agree.
Return solidVolume = measuredVolume*(1-voidFraction) and estimatedMass = solidVolume*solidDensity.
When to use this tool
Use Waste Bin Void Share Correction when reconciling supplied environmental masses, solids fractions or material volumes.
How to use the tool and how it works
- Enter measuredVolume, voidFraction, solidDensity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read solidVolume, estimatedMass. Use the output convention below.
Require nonnegative measuredVolume and solidDensity and voidFraction in [0,1]. Return solidVolume = measuredVolume*(1-voidFraction) and estimatedMass = solidVolume*solidDensity. Density must be mass per volume of the nonvoid solid on the chosen unit basis.1

}Limitations and assumptions
- A voidFraction of one gives zero solid volume and mass. This assumes the supplied void fraction and solid density describe the bin contents; it does not measure compaction, moisture or changing material composition.
- 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 density, method-specific moisture procedures and uncertainty analysis where simple homogeneous-material assumptions are insufficient.
