    en.wikipedia.org/wiki/Barlow's_formula

    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.

    Speer Gold Dot 124gr 9mm+P in SIG P226 magazines. Overpressure ammunition, commonly designated as +P or +P+ (pronounced Plus-P or Plus-P-Plus), is small arms ammunition that has been loaded to produce a higher internal pressure when fired than is standard for ammunition of its caliber (see internal ballistics), but less than the pressures generated by a proof round.

    Maximum Allowable Operating Pressure (MAOP) is a pressure limit set, usually by a government body, which applies to compressed gas pressure vessels, pipelines, and storage tanks. For pipelines, this value is derived from Barlow's Formula , which takes into account wall thickness, diameter, allowable stress (which is a function of the material ...
