Thickness of shells under external pressure for Cylinders having values $D_o/t≥ 10$

Values for calculation

$T$ $\mathrm{°C}$
$P$ $\mathrm{MPa}$
$D_o$ $\mathrm{mm}$
$L$ $\mathrm{mm}$
$t$ $\mathrm{mm}$
$D_o/t$
$L/D_o$
$A$
$B$ $\mathrm{MPa}$

Calculation

Calculated value of maximum allowable external working pressure for the assumed value of $t$

$$P_a=\cfrac{4\cdot B}{3\cdot \left(D_o/t\right)}$$$$P\le P_a$$

Requirements

$$D_o/t \geq 10$$
