Liquidity Index

Liquidity index, abbreciated as \(l_l\), is the range of water content to the liquid limits.

 

Liquidity Index formula
\( l_l =  w - w_p \;/\; l_p  \)
Symbol	English	Metric
\( l_l \) = liquidity index	\(dimensionless\)
\( w \)  = natural water content	\(dimensionless\)
\( w_p \)  =  lower plastic limit (plastic limit)	\(dimensionless\)
\( l_p \)  = plasticity index	\(dimensionless\)
