Barlow's Formula
P = (2 t s) / D |
Barlow's Formula is an easy method of predicting the bursting pressures of pipe and tube that are within actual test bursting pressures. |
P = |
internal units pressure, psi |
S = |
unit stress, psi |
D = |
outside diameter of pipe, inches |
t = |
wall thickness, inches |
