Barlow's Formula

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

Barlow's Formula ( \(Ba\) ) relates to burst pressure, the point just before or at when a pipe or tubing fails under pressure.

Barlow's formula

\(\large{ p_b = \frac{2  S  t}{d}  }\) 


\(\large{ p_b }\) = burst pressure

\(\large{ S }\) = allowable stress

\(\large{ d }\) = pipe diameter

\(\large{ t }\) = pipe thickness
