A. Determine the percent finer than each sieve and plot a grain-size distribution curve
Develop a spreadsheet for the computations and plotting required for problems and make sure to turn on "minor gridlines" for the grain size axis. Please present the grain size distribution in semi-log scale.
B. Determine D10, D30, and D60 from the grain-size distribution curve.
C. Calculate the uniformity coefficient, Cu.
D. Calculate the coefficient of graduation, Cc.
