I'm asked to make a calculation for a pressure can, so I made a calculation according the ASME VIII code.
In this code there is a difference between Internal and External pressure. And I am struggling with the external pressure section.
In my assignment the design pressure is 10 Barg Internal pressure and also Full Vacuum.
If I am correct Full Vacuum results into External pressure where a specific pressure is generated from the outside.
But what is the pressure I should take into account? What is the pressure value for full vacuum.
Or am I totally wrong about the Full Vacuum being External Pressure?
