    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, theFile Size: 2MB

    There are almost no interactions between individual atoms or molecules of the tracer gas. The molecular flow regime is dominant at leak rates lower than 10-8 Pa m3 s-1. The transition between laminar-viscous flow and molecular flow is not instantaneous. The transition regime is called Knudsen flow.

    A micro-tube capillary leak element is a flexible tube with a very small ID through which gas flows at a rate that is nearly proportional to the differential pressure across it. The leak rate of a micro-tube leak element has a positive temperature dependency of about 0.1% per &C for reservoir-style leaks, and -0.6% per &C for open-style leaks.
