The Toolkit

Diameter and length to the last litre.

Diameter times length to the last litre — fill volumes for flooding, hydrotest, and dewatering planning.

How this is calculated.

A pipe is a cylinder: volume is π times the internal radius squared times the length. The same figure is the water you will need to flood it for a pig run or hydrotest.

V = π · (D/2)² · L
bbl = m³ × 6.28981
litres = m³ × 1000

Questions

Barrels or cubic metres?

Both — results render in m³, bbl, and litres simultaneously.
