1
Q
A soil sample has a void ratio of 0.65 and a specific gravity of 2.65. What is its porosity?
A
n= e/1+e = 0.65/1+0.65 = 0.395 (or 39.5%)
2
Q
A fully saturated soil has a volumic density of 21 kN/m³. What is its void ratio if the grain density is 2600 kg/m³?
A
e= γsat−γw/γs−γw
3
Q
A soil sample with an initial wet weight of 135.5 g dries to 105.5 g. What is the moisture content?
A
w=mwet-mdry/mdry x 100
