Software pack Printer Equipment for measuring
density
An easy way for measuring
density in a laboratory
consists of determining
the the weight and the
volume of the object and
to make the following
calculation: density [kg/m³]
is equal to mass [kg]
divided by volume [m³].
The volume of liquids is
determined by normal
means for determining
volume. To perform this
function you will
require flasks, cylinders
and pipettes.
With solids, volume can
be calculated taking
into consideration its
specific form, such as
cubes. For complicated
shapes, the object can
be placed into a
cylinder full of water.
The change in the level
of the liquid will
indicate the real volume
of the object.
Measurement of density
using hydrostatic densimeters
According to the
principles of buoyancy
for an object submerged
in a liquid, a force is
generated from the
bottom up to the top.
This force is called
displacement. The change
in displacement
corresponds to the
amount of liquid shown
to be in the cylinder.
Also, the force by
weight of the object is
equivalent to the change
in the volume of liquid.
