Problems $9-12.$ A field compacted of sandy loam was found to have a wet

density of $2181k\frac{g}{m^3}$ at a water content of $10$ percent. The maximum dry

density of the soil obtained in a Standard Proctor test was $2000k\frac{g}{m^3}.$

Assume specific gravity to be $2\mathrm{.}65.$ Compute the following:

c$.19\mathrm{.}73k\frac{N}{m^3}$

b$.19\mathrm{.}67k\frac{N}{m^3}$

d$.19\mathrm{.}82k\frac{N}{m^3}$

Compute for the dry unit weight at zero voids.

a$.19\mathrm{.}23k\frac{N}{m^3}$

c$.20\mathrm{.}20k\frac{N}{m^3}$

b$.19\mathrm{.}78k\frac{N}{m^3}$

d$.20\mathrm{.}55k\frac{N}{m^3}$

Compute for the degree of saturation.

a$.78\mathrm{.}25\%$

c$.78\mathrm{.}77\%$

b$.78\mathrm{.}57\%$

d$.78\mathrm{.}88\%$
