I guess you may check any steam trap sizing software on line.

The Spirax Sarco website (linked below) has an excellent guide to steam trap selection, sizing and installation.

Remember that normal operation steady state is not your only operating scenario - don't forget cold start-up. Each drip leg should have a manual drain, but you will save a lot of operator grief if you parallel the selected traps with thermostatic traps.

Thermodynamic traps can seem ideal but often malfunction in the rain and cold temps. Spec with caps if this is likely.

Vacuum breaks are also worth reading about.
