Density (T) --> Density (15°C)
This function converts a density value at the observed temperature to the density at 15°C according to
the API 1952 Table 53.

Boundaries
Table 53 contains values for the following range:
Input value Normal Range EU
Observed density 420 .. 1099 kg/m3
Observed temperature -25 .. 125 °C
Note that the table does not cover the full range, e.g. for an Observed specific gravity of 0.420 the table
only specifies values between 45 .. 60 °C

Calculation
out of range With respect to the standard the input
values are:
0: In Range
1: Out of Range - OOR 0
Calculations
The table values are the standard, so no calculations are involved. The function performs an
interpolation between the table values that correspond to the input specific gravity and input
temperature.
In case the combination of input values ('Observed density' and Observed temperature') is not covered
by the table, the output 'Density at 15 °C' is set to 0 and output 'Calculation out of range' is set to 1.
