Allowable Pressure Calculations for Tubing Diameter Using Barlow's Equation in MATLAB

This document presents a MATLAB implementation for calculating the allowable pressure of thin-walled tubing using Barlow's equation. The analysis focuses on tubing diameters of 1/4", 3/8", and 1/2", with a constant wall thickness. The allowable tensile strength of the tubing wall is taken into account to compute the permissible internal pressure for each tubing diameter. Results are visualized in a plot showing the relationship between tubing diameter and allowable pressure. The calculated pressures are: 14822.92 psi for 0.25", 9881.95 psi for 0.38", and 7411.46 psi for 0.50".
