Equations

Density of Test Item

The density of the test item was calculated using the following equation:

p = (m3 - m1) / (m2 -m1) * p(H2O)

with

p = density in g/cm3

m1 = mass of empty pycnometer in g

m2 = mass of pycnometer with water in g

m3 = mass of pycnometer with test item in g

p(H2O) = density of water at test temperature (0.9982 g*cm-3 at 20.0 °C)

The relative density of the test item has the same number value, but no unit.
