I think I may have not explained the point I was making properly... Yes, you still have 1/2" PSI (like I said) but 1/2" PSI acting on the the 500 sq inch surface area of the tank walls (or a piston if that makes it easier to understand what I was referring to) can lift 250 lbs, and on those 500 Sq inch walls, you have 250 Lbs of force spread out evenly try to push the wall out... That's all I was trying to say as maybe that's what are poster was referring to.....

As to exhaust pressure limits and diesel engines that was asked above-- Most manufacturers of realitively modern engines have maximum limits in the 1-2 psi range (20-60 inches of water column or 2-5 " Hg) .. These numbers are close enough for most preliminary exhaust design work..

Yes, you guys take no prisoners..
