Formulas
To allow for the buoyancy of the wires, subtract the buoyancy "A" caused by the
immersed wires from the buoyancy determined for the sample:
G = W (a) – W (fl) . The buoyancy value "A (corr)" which is to be used in the
calculation is then: G – "A" .
A (corr) = [W (a) – W (fl)] – 2 ·
A (corr) = 1 – 2 ·
In this density determination kit, the beaker with the larger diameter (d 90 mm) and
an immersion device with two wires with a diameter of 0 .7 mm are used to determine
the density of solid objects .
When the values d = 0 .7 mm and D = 90 mm are used, the correction factor is:
0.7

= 0.99983

When using devices with other dimensions, the correction factor must be recalculated
accordingly .
