$5.(15$ points$).$ A pump test on a confined aquifer, under non$-$equilibrium conditions. An observation well located $150$ m away from the pumping well recorded a drawdown shown on the table below. Use the Jacob straight line method to determine the aquifer's transmissivity $($T$),$ and the storage coefficient $($S$).$ Note: Jacob's equation is a symplification of Theis equation; the simplyfication is only valid for small values of $\backslash ($ u $\backslash ),$ eg $\backslash (\backslash$mathrm$\{$u$\}<mn>0</mn><mn>.</mn><mn>0</mn><mn>3</mn><mtext></mtext><mi>\backslash </mi><mi>)</mi>$
