Formula that relates characteristics of the pipe and internal pressure it can withstand
Barlow's formula (called "Kesselformel"[1] in German) relates the internal pressure that a pipe[2] can withstand to its dimensions and the strength of its material.
This approximate formula is named after Peter Barlow, an English mathematician.[3]

where
- : internal pressure,
- : allowable stress,
- : wall thickness,
- : outside diameter.
This formula (DIN 2413) figures prominently in the design of autoclaves and other pressure vessels.
