Output
density Meaning depends on the input
'Conversion method'.
'Conversion method' = 1
Density at 15 °C and the
equilibrium pressure.
'Conversion method' = 2
Density at the observed
temperature and pressure
kg/m3 DENS 0
CTL Volume correction factor for
temperature.
Value will be rounded according
to input 'API2540 rounding'' - CTL 1
CPL Volume correction factor for
pressure
Value will be rounded according
to input 'API 11.2.1M rounding'' - CPL 1
CTPL Combined volume correction
factor
CTPL = CTL * CPL - CTPL 1
K0 Actual value of constant K0 used
for CTL calculation - K0 0
K1 Actual value of constant K1 used
for CTL calculation - K1 0
K2 Actual value of constant K2 used
for CTL calculation - K2 0
Alpha Thermal expansion factor 1/°C ALPHA 0
F Compressibility factor - F 0
Product When input 'Product' is 'B - Auto
select', then the output is set to
the actual selected product of
tables 53B/54B (enumerative
value as defined for input
'Product'), else the output is set
equal to input 'Product'. - PRDCUR 0

Calculations
The calculations depend on the conversion method.
Conversion method 1: from observed to standard conditions.
The function performs the following iterative algorithm to calculate the density at reference conditions:
