Flate Head Design Pressure 1

[chuckoehler]

When designing in Compress for an atmospheric vessel, is it necessary to use 14.7 as the internal pressure? Can I use 0psi? Also, does Compress take into account the actual weight stress from the liquid or do I have to enter these manually as a vertical load? I want to make sure that the thickness if using 0psi is still adaquate for the the weight and any possible oil canning that could occur.

Use 0 psi and set liquid level and S.G. by going to: Loads/Liquid Level
