An organic soil, the void ratio e is found to be 10.0 and GS is .2.35 If this soil is fully saturated, find:a. Unit weight of the soilb. water conten w%c. Does this soil sink in water?
A sample of soil was tested; the results were
void ratio e = 1.024
moisture content w = 33.4%
specific gravity of solids Gs = 2.75
Using a phase diagram, determine the following:
a) The soil's bulk, dry and saturated unit weights, and degree of
saturation;
b) The volume of air void in 1m^3 of this soil; and
c) The weight of water required to fully saturate the 1m^3 soil
Discuss the effect of void ratio, particle size distribution,
and effective stress on soil behaviors (e.g., hydraulic
conductivity, deformation and strength) respectively.
. Draw a plot of the following set of data
and determine the linear regression equation. What is
the
value of the slope and
intercept? What is r and
R2? Are there any outlier
values? (15 points)

Construct a time series plot. What type of pattern exists in the data?
The time series plot indicates a linear trend and a seasonal pattern
Show the four-quarter and centered moving average values for this time series.
Compute seasonal indexes and adjusted seasonal indexes for the four quarters.
