I have the following questions for sizing steam line:

 

what property package to select for sizing steam lines? Peng-Robinson or NSB Steam?

what is swage abrupt?

How to determine the number increments? Thanks

- For only steam case, use ASME Steam or NSB Steam Package, NSB is better specially near critical conditions.

- swage abrupt, a 180 degree swage rather than 45 degree.

- number of increments: must be enough to have for each increment dP < 10% of the inlet pressure, if dP exceed 10% then you need to increase the number of increments.
