a soil sample $10$ cm in diameter is placed in a tube $1$ m long. a constant supply of water is allowed to flow into one end of the soil at a$,$ the outflow at b is collepted by a beaker. the average amount of water collected is $1$ cm$3$ for every $10$ seconds. the tube is inclined as shown in the figure. determine the $($a$)$ hydraulic gradient, $($b$)$ flow rate, $($o$))$ average velocity, $($d$)$ seepage velocity if e $=0\mathrm{.}6,$ and $($e$)$ hydrauli conductivity.
