Calculation method
Calculation method
Void ratio e
Void ratio=particle density/dry density−1; porosity=e/(1+e).
Porosity (%)
Void ratio=particle density/dry density−1; porosity=e/(1+e).
Symbols and units

- b
- Dry soil density (g/cm³)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Void ratio=particle density/dry density−1; porosity=e/(1+e). Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
