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

\(\large{ \sigma_h = \frac{ p_i \; r_i^2 \;-\; p_e \; r_e^2 }{ r_e^2 \;-\;r_i^2 } }\) 
 Symbol English Metric
\(\large{ \sigma_h }\)  (Greek symbol sigma) = hoop stress \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ p_e }\) = external pressure \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ p_i }\) = internal pressure \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ r }\) = radius to point of intrest \(\large{ in }\) \(\large{ mm }\)
\(\large{ r_e }\) = external radius \(\large{ in }\) \(\large{ mm }\)
\(\large{ r_i }\) = internal radius \(\large{ in }\) \(\large{ mm }\)
