Density according to GOST R 50.2.076-2010

On this page the algorithm of working with the "Density : GOST R 50.2.076-2010 (15°C)" tab is presented.

Reduction of the measured density to 15°C and calculation of the actual density

1. To bring to 15°C, enter in the appropriate fields the density measured by the areometer and the temperature at which the measurement was made.
2. If you want to take into account the thermal expansion of the areometer glass, mark the corresponding check-box.
3. Select the group to calculate: crude oil (density from 611,2 to 1163,8 kg/m3), oil products (density from 611,2 to 1163,9 kg/m3), lubricating oils (density from 801,3 to 1163,9 kg/m3).
4. Click on the "Calculate" button to get the result.
5. To determine the actual density, enter the density at 15°C (for example, from the certificate) and the temperature at which to recalculate.
6. If the measurement was carried out under pressure, mark the checkbox "Take into account the excess pressure" and enter the figure.
7. Select the group to calculate.
8. Click on the "Calculate" button to get the result.
9. To change temperature units, you can use the context menu of the unit field (right mouse button) or double-click on this field (units will vary in a circle). If you check the "Recalculate when changing units" checkbox in the context menu, the program will recalculate the value in the "Temperature" field "on the fly." In settings, you can change the units for all tabs of the program at once.
10. To change pressure units, you can use the context menu of the unit field (right mouse button) or double-click on this field (units will vary in a circle : megapascals -> bars -> technical atmosphere (kg/cm2, kgf/cm2) -> pound per square inch). If you check the "Recalculate when changing units" checkbox in the context menu, the program will recalculate the value in the pressure field "on the fly." In settings, you can change the units for all tabs of the program at once.

Conversion of density from one temperature to another

1. Unlock the conversion button using the "Density to density" checkbox.
2. Enter the density measured by the areometer and temperature at which the measurement was made.
3. If you want to take into account the thermal expansion of the areometer glass, mark the corresponding check-box.
4. Select the group to calculate.
5. Enter the temperature at which to recalculate.
6. If the measurement was carried out under pressure, mark the checkbox "Take into account the excess pressure" and enter the figure.
7. Select the group to calculate.
8. Click on the arrow button.
9. In the bottom field "Actual density (kg/m3)" you'll get the result. Density at 15°C can be seen in the appropriate fields.
