2 Phase Flow Calculation with Aspen Plus

[Midix]

Somebody experience with the pipe model for determining the flow regime. Is it trusable for using it for linesizing?

I have a different software (PRODE PROPERTIES with Excel, see prode.com)
however the basis for the calc's should be about the same,
problems being evaluation of fluid properties as viscosities etc.
for hydrocarbons you can select Beggs & Brill and generally obtain good results,
for other fluids you can consider other empirical methods as Martinelli etc.
again take care to select the correct package fluid properties.
