  • Fundamentals of leak detection - Leybold

    The leak rate of a vessel indicates the amount of gas flow which escapes through the walls of the vessel. It must be noted, however, that the leak rate for a leak depends on the type of gas. If the gas temperature T and the molar mass M of a gas G is known, the gas mass flow can be calculated from the leak rate

  • Impact of leaks in sulfur hexafluoride and nitrogen

    Oct 19, 2018This is correct, but the impact of inspiratory leaks in SF 6 MBW systems is entirely different because SF 6 is washed out with air. Therefore, an inspiratory leak does not affect the SF 6 concentration but only inspiratory flow, which is not used to calculate FRC or LCI. Consequently, the SF 6 MBW method is insensitive to inspiratory leaks.
