Problem $2$

The following data were obtained from a liquid limit test on silty clay.

$\backslash$table$[[$No$.$ of Blows,Water Content, $\%],[35,41\mathrm{.}1],[29,41\mathrm{.}8],[21,43\mathrm{.}5],[15,44\mathrm{.}9]]$

Two plastic limit determinations had water contents of $23\mathrm{.}1$ and $23\mathrm{.}6$ percent. Plot the flow curve based on the given data. Determine the LL$,$ PI$,$ flow index, liquidity index, consistency index, and toughness index. The natural water content of the soil was found $30\%.$
