The Self-Venting Flow Line Calculator is used to size self-venting, vertical pipes and tubes, or to size pipes and tubes for side-outlet applications. This calculator uses three pipe schedules: SCH 40, SCH 80 and SCH 160. The actual and nominal line sizes required for self-venting flow are measured in inches.
