Any other information on results incl. tables

The relative density value at 20°C was calculated according to the formula:

 

                                      0. 9982 x (W4 - W3)

Density (g/ml) = ____________________________

                                   (W2 - W1) - (W5 - W4)

 

where:

W1      =         Weight of pyknometer for WE determination (g)

W2      =         Weight of pyknometer filled withwater(g)

W3      =         Weight of pyknometer (g)

W4      =         Weight of pyknometer with an amount of the test item (g)

W5      =         Weight of pyknometer with test item and filled withwater(g)

0.9982            Tabulated value for the specific gravity of distilled water at 20°C (g/mL)

The specific gravity of the test item at 20°C is determined by the ratio between the mass of a volume of the test item and the mass of the same volume of water: it was obtained according to the formula:

 

                                                                                   density (g/mL)

                                               Specific Gravity = _______________

                                                                                   0.9982 (g/mL)

 

Since the density of distilled water at 4°C is 1.0000 g/mL, the relative density, (D204) defined as the ratio between the mass of a volume of the test item at 20°C and the mass of the same volume of water at 4°C, is the dimensionless numeric value of the density.
