Definitions
Bulk (natural) saturated dry and submergeddensities (ρ) are defined in a similar mannerHere you can also use mass (kg) instead of weight (kN)γ g = ρ = MVWhereγ =Nm3 g= ms2 ρ = kgm3
21
Specific Gravity
22
Specific Gravity In Terms of Density
23
Relationship between parameters
These definitions can be used to determine any desired relationships between above quantities and hence to determine void ratio degree of saturation etc That can not be measured directly by laboratory tests Some relationships are as follows
