Pressure vessel

  1. Jul 14, 2015 #1
    When a pressure vessel is subjected to internal pressure of 3 bar and external pressure of 4 bar..Is it right to say resultant pressure is 1 bar external? Does both cases (3 bar int& 4 bar ext,only 1 bar ext) produce the same result considering all other factors like thickness,material etc constant?

    Seems OK.

    You are probably correct. A pressure vessel is usually designed for a differential pressure.
    But there may be a complexity. The access hatches and seals in a pressure vessel may be designed to work for positive internal pressures only.
