Problem 1 (7 Marks)(CLO1, SO1) The grain size analysis test is performed to determine the percentage of each size of grain that is contained within a soil sample, and the results of the test is shown as below: A. Calculate( in a table) the percent retained and the percent finer through each sieve (Hint: Total weight of the soil sample=sum of retained soil on each sieve) B. . Find the percent of Gravel, $\%$ of sand \& $\%$ of Fine from the table?? (Hint: Without Drawing) C. . (If D10 $=0.017,\mathrm{D}30=0.22,\mathrm{D}60=0.3$ ) Find the coefficient of uniformity \& the coefficient of curvature ? D. If $\mathrm{Cc}=3\&\mathrm{Cu}=5,\%$ of Gravel $=30\%,\%$ of $\mathrm{Sand}=67\%$, and $\%$ of fine $=3\%$, is the sample soil is well graded or poorly graded? Why?
