No. 200 sieve.
a. Complete the table by calculating the values based
on the information supplied.
b. Using five-cycle semilog paper, plot the grain size
distribution for this sieve analysis.
c. Give the D60 and the D10 values for this sieve
analysis. Calculate the k value for this analysis
using Hazen's approximation, which states that
k (cm/sec) = 100D10² (D10 in mm).
