CE Board HGE Problem 22 (Hydraulics and Geotechnical Engineering) - CE May 2014

The total density of a sand in an embankment was found to be 1900 kg/m^3 and
the field water content was 11.5 %. In the laboratory, the density of solids was found to be 2660 kg/m^3 and the maximum and minimum void ratio are 0.62 and 0.44 respectively.

a. What is the dry density of the sand ?
b. What is the void ratio of the sand ?
c. calculate the relative density of the sand in the field.
