Archimedes' principle states:
An object immersed in liquid will be subject to a buoyant force (G) . This force is equal
to the weight of the liquid displaced by the object . The volume of the immersed object
V (s) is equal to the volume of the displaced liquid V (fl) .
The following are determined:
1 . Weight in air W (a)
2 . Buoyancy of the object in the liquid (G)
The density of an object is:
mass of object W (a) W (a)
ρ = = =
volume of object V (s) V (fl)
If the density ρ (fl) of the displaced liquid is known:
Mass (fl) G
V (fl) = =
ρ (fl)
ρ
Thus:
W (a) · ρ (fl)
ρ =
G
