Calculation method
Calculation method
Liquid limit at 25 blows (%)
Least-squares water content versus log10(blows); liquid limit is predicted water content at 25 blows.
Flow index (% per log10 blow)
Least-squares water content versus log10(blows); liquid limit is predicted water content at 25 blows.
Regression residuals (JSON)
Least-squares water content versus log10(blows); liquid limit is predicted water content at 25 blows.
Symbols and units

- Blow counts (count)
- b
- Water contents (%)
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; Least-squares water content versus log10(blows); liquid limit is predicted water content at 25 blows. 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.
