The approach used here, and in the Excel spreadsheet, is approximate only.Regarding Item 4, the effective release point, the same assumption has been made for all inlet types: the dispersed phase is released uniformly over the vertical height of the continuous phase at the centerline axis of the vessel at the start of the gravity separation sectionbasically at the perforated plate location. The procedure then to calculate the drag coefficient is to calculate the Archimedes number, Ar, as defined in Eq.
