A soil has a natural water content of 10%, specific gravity of 2.65, and porosity of 0.45.
a) Find the dry unit weight and degree of saturation.
b) If the optimum water content for the soil from a standard proctor was 20%, how much water would have to be added to 1m^3 of the soil to increase the water content to an optimum level?

The flow of water through soil depends on the porosity of the
soli which is assumed to be normally distributed. To compare two
types of sandy soil n1=16 measurements are to be taken on the
porosity of soil A and n2=21 measurements are to be taken on soil B
Assume that the two sample variances S12= 0.01, S22= 0.02.
(a) construct a 95% confidence interval for ratio of variances
(variance2/variance1). Is there any evidence that
two population variances are qual....

. A 0.65 specific gravity natural gas contains 10% nitrogen, 8%
carbon dioxide, and 2% hydrogen sulfide. Brill and Beggs
correlation can used in estimating the z-factor values accurately
enough for many engineering calculations. Brill and Beggs’ z-factor
correlation is expressed as follows: With your knowledge in
computer literacy and information technology coupled with Matlab
programming, develop either a Microsoft excel spreadsheet program
or a Matlab script to compute the z-factor of the gas at initial
pressure and temperature of...

: A wet soil sample with a water content of 15% and percentage
air voids of 20% was oven dried. If the soil sample is cylindrical
in dimension with length as 100 mm and diameter as 50 mm, then how
much mass of water is present in the soil? Also calculate the mass
of soil. Assume specific gravity of soil is 2.69 Interpret your
answer and conclude how water content influences the unit weight of
soil.
