Problem $1/$ Probleem $1$

The graph below shows the result of an oedometer test on saturated clay. The graph is of compression gauge reading versus time. At the beginning of the load increment the test specimen was $18\mathrm{.}343$ mm thick, and it was drained to both sides $($open specimen$).$ Use the average height of the specimen during the increment to calculate the length, $\backslash ($ d $\backslash ),$ of the drainage path and determine from the graph the value of the consolidation coefficient, $\backslash ($ c$\_\{$v$\}\backslash ).$
