Note: π = 3.14159

Pipeline volume calculation = π × radius 2 × length.

Computing Pipeline Capacities

(Inside Diameter) 2 x 0.0408 = gallons per foot

Example: Inches to CM (6” x 2.54) ÷ 100 = 0.1524 M Diameter ÷ 2 = 0.0762 M Radius 3.14159 x (0.0762 M x 0.0726 M) x 1 M = 0.01824 M 3 per Meter x 1000 = 18.24 Litres per Meter

Gallons to US Barrels multiply by 0.02380952
