Description
Return a wet-aerosol density under additive liquid volume.
Particle and droplet terms depend on size representation, weights, density, drag and logarithmic-bin conventions. A spherical growth or low-Reynolds approximation is a local model term rather than a measured size distribution, composition or health/exposure assessment.
Return a wet-aerosol density under additive liquid volume.
When to use this tool
Use Aerosol Wet Dry Density Factor when checking the stated particle, droplet, drag, growth or bin-basis convention.
How to use the tool and how it works
- Enter dryDensity, liquidDensity, wetVolumeFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read wetDensity, liquidVolumeFraction. Use the output convention below.
Return a wet-aerosol density under additive liquid volume. Require dry/liquid densities > 0 and wetVolumeFactor >= 1; wetDensity = (dryDensity+liquidDensity*(factor-1))/factor, liquidVolumeFraction = (factor-1)/factor.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| dryDensity | Dry Density | Required. Finite number; strictly above 0. |
| liquidDensity | Liquid Density | Required. Finite number; strictly above 0. |
| wetVolumeFactor | Wet/dry particle volume ratio >=1, not diameter growth factor. | Required. Finite number; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| wetDensity | Wet Density | Required. Finite number. |
| liquidVolumeFraction | Liquid Volume Fraction Unit: 1. | Required. Finite number. |

}Limitations and assumptions
- The factor is wet/dry volume, not diameter growth; volume additivity, composition and actual particle state are supplied assumptions.
- 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 particle measurements and an appropriate complete distribution/transport model with justified material, shape and flow assumptions for atmospheric inference.
