A soil specimen $5cm$ in diameter and $12cm$ in length was placed within a falling head

permeameter of the type shown in Figure $7\mathrm{.}5b$ in your textbook. The inner diameter of standpipe

is $1cm.$ Given the reduction in standpipe water level from $105cm$ to $99cm$ in $100$ minutes, $($a$)$

compute the hydraulic conductivity of the specimen in $c\frac{m}{sec}$ and $f\frac{t}{?}$ day and $($b$)$ make a

preliminary judgement of the likely soil type based on the computed hydraulic conductivity.
