When there are small quantities of flash steam and a large amount of condensate
(e.g., open systems pumping large amounts of super-cooled condensate)
Consult the sizing tables in sections (1) and (2).
Select the condensate receiver size based on the larger of (1) and (2)..
Select the vent pipe diameter and overflow pipe diameter from (1).
