  • 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

  • Sealing Sense What determines seal leakage?

    according to EPA Method 21. An emission rate of 1,000-ppm is equal to a mass leakage rate of 5.6-g/hr. Another rough rule of thumb is that a milliliter of liquid contains about 20 drops; therefore, a volumetric leakage rate of 3-ml/hr would be about 60 drops per hour or a drop per minute. Some states, notably California, have a “no visible leak-
