    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
