P100 Correlation
0: Disabled
The standard correlation is commonly
used for pure products such as propane,
butane and natural gasoline. It only
requires the relative density and the
temperature to calculate the vapor
pressure
1: Enabled
The improved correlation requires the
vapor pressure at 100°F (37.8 °C). This
method is better suited for varied NGL
mixes Where different product mixes
could have the same specific gravity but
different equilibrium pressures.
