NOCONV 1
Output density Depending on the conversion
method this represents the density
either at 15
°
C and the equilibrium
pressure or the observed
temperature and pressure
kg/m3 DENS 0
CTL Volume correction factor for
temperature.
Value will be rounded according to
input 'API 11.2.4 rounding' - CTL 1
CPL Volume correction factor for
pressure
Value will be rounded according to
input 'API 11.2.2M rounding' - CPL 1
CTPL Combined volume correction factor
CTPL = CTL * CPL - CTPL 1
F Compressibility factor
The output value will be either
rounded or not depending input
'API rounding' 1/bar F 0
Equilibrium
pressure The equilibrium pressure calculated
by GPA TP-15
Will be set to 0 when equilibrium
pressure is below atmospheric
pressure bar(a) EQUIPC
UR 0
CTL calc out of
range With respect to the API 11.2.4
standard the combination of input
values is:
0: In Range
1: Out of Range
The following range checks apply:
Conversion method 1: observed ->
standard

0.21 <= RD <= 0.74
with RD = Input density /
999.016/CPL

-46 <= T <= 93 °C
