the calculations are performed in accordance with the rounding and truncating
rules of the standard.
5.
The CPL value is calculated from the compressibility factor and the 'Observed
pressure' and 'Equilibrium pressure' input values.
6.
The Density at [15
C, equilibrium pressure] is calculated by dividing the Observed
Density by the CTL and the new CPL value.
7.
Steps 2 through 6 are repeated taking the Density value from step 7 as the start
value for the next iteration until the absolute difference between two
consecutive Density values is 0.0001.
Conversion method 2: from standard to observed conditions.
The function performs straightforward calculations to determine the Density at observed conditions:
1.
The CTL value is calculated according to API 1952 Table 54
2.
The compressibility factor is calculated according to API MPMS 11.2.1M from
the input density and temperature'. If API 11.2.1M rounding is enabled then the
input density and temperature are rounded and the calculations are performed
in accordance with the rounding and truncating rules of the standard.
3.
The CPL value is calculated from the compressibility factor and the 'Observed
pressure' and 'Equilibrium pressure' input values.
4.
The output Density (at observed temperature and pressure) is calculated from
the input Density and the CTL and the CPL values.
