Description
Return diameter and volume growth from a supplied factor.
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 diameter and volume growth from a supplied factor.
When to use this tool
Use Aerosol Hygroscopic Growth Volume Factor when checking the stated particle, droplet, drag, growth or bin-basis convention.
How to use the tool and how it works
- Enter dryDiameter, growthFactor. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read wetDiameter, volumeFactor. Use the output convention below.
Return diameter and volume growth from a supplied factor. Require dryDiameter >= 0 and growthFactor >= 1; wetDiameter = dry*factor, volumeFactor = factor³.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| dryDiameter | Dry Diameter | Required. Finite number; minimum 0. |
| growthFactor | Growth Factor | Required. Finite number; minimum 1. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| wetDiameter | Wet Diameter | Required. Finite number. |
| volumeFactor | Volume Factor | Required. Finite number. |

}Limitations and assumptions
- This assumes geometrically similar particles; hygroscopic equilibrium, composition and actual relative humidity are not 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 particle measurements and an appropriate complete distribution/transport model with justified material, shape and flow assumptions for atmospheric inference.
