Longitudinal Stress Thick-walled Section (Internal & External Pressure) Formula

\( \sigma_l =  p_i \; r_i^2 - p_e \; r_e^2 \;/\; r_e^2 - r_i^2 \) 
Symbol English Metric
\( \sigma_l \)  (Greek symbol sigma) = longitudinal stress \(lbf\;/\;in^2\) \( Pa \)
\( p_e \) = external pressure \(lbf\;/\;in^2\) \( Pa \)
\( p \) = internal pressure \(lbf\;/\;in^2\) \( Pa \)
\( r_e \) = external radius \( in \) \( mm \)
\( r_i \) = internal radius \( in \) \( mm \)
