Hi friends, some of you use calculation 
progammes for pressure hulls. 
I use tables which are older. 
May some of you can cross check
the dive deep ?

I can buy an older bigger Psub with the 
following dimension: (1 inch = 24,5mm) 

Diameter outside = 2400 mm (98 inch) 
thickness hull   =   15 mm (0,61 inch)
frame distants	 = 2450 mm (100 inch)
Steel : normal working steel, mild steel

any cross check welcome, regards Carsten.
