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

$$ D_o/t \geq 10 $$
