Problem 135 Calculate the minimum wall thickness for a cylindrical vessel that is to carry a gas at a pressure of 1400 psi. The diameter of the vessel is 2 ft, and the stress is limited to 12 ksi.

Solution 135

$12\,000 = \dfrac{1400(2 \times 12)}{2t}$

$t = 1.4 \, \text{ in}$ answer

why should we multiply by 12 in diameter

For us to get the thickness, We must convert the ft to inch. (1ft=12inch). Because the unit of the pressure is pounds per square inch.
