Barlow's Formula

Written by Jerry Ratzlaff on . Posted in Fluid Dynamics

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

  • Abbreviated as Ba

formula

\(p_b = \frac{2  S  t}{d} \;\) 

Where:

\(p_b\) = burst pressure

\(S\) = force maximum allowable tensile strength

\(t\) = nominal thickness

\(d\) = outside diameter
