Dear friends,

I have 2 years experience in designing pressure vessels.I have designed many Circular Pressure vessels. But this is the first time I am doing a Rectangular type.

Can anyone please answer for my doubt.
The details of the problem is,
Design of Rectangular tank
Size 1500 length x 800 width x1200ht mm with two different conditions
1. Internal pressure 1 kg/cm2
2. Absolute vacuum
Material: MS ; Medium: Air

To find: Thickness of the tank, Stiffener size
Corrugated type of tank is preferable or not.

I had gone through Appendix 13 in ASME Sec V111 Div 1 and Megysey book Rectangular tank under Hydrostatic pressure topic(pressure is not considered, thickness is calculated generally for the required size). But still I did not get the proper formula to find thickness for varying pressure.

Please help me.

Expecting your reply. Please reply as soon as possible. I need it urgently.

Thanks a lot.

With kind Regards
