pressure vessel (PV)


ECSS-E-ST-32-02C Rev. 1


pressurized hardware designed primarily for the storage of pressurized fluid with an energy level greater than or equal to 19310 Joules, or with a pressure greater than or equal to 0,69 MPa, or which can create a hazard if released


  • NOTE E.g. the stored energy can be calculated by the formula for the reversible adiabatic (isentropic) expansion of the confined gas: where: E is the stored energy P1 is the internal pressure P2 is the external pressure V is the pressurized volume g is the ratio of specific heat of the gas.
