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 corrected buoyancy
"A (corr)" to use in this calculation is then: G – "A�"

The specific gravity determination kit uses the large-
volume beaker (90 mm d) and an immersing device
with 2 wires (0�7 mm diameter) for the determination
of the specific gravity of solids�
When the values d = 0�7 mm and D = 90 mm are
plugged into the equation, the correction factor is:

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