A natural helium leak in Southern California reveals that the Newport-Inglewood fault is deeper than once thought — with a direct line from the Earth's surface to the planet's hot, dense mantle. Helium-3 comes only from the Earth's mantle, the semisolid rock layer beneath the crust. "The fault, which I don't think people had anticipated, was deeply connected," said Jim Boles, a professor ...
Any leaked gases inside the airtight chamber surrounding the part under test are detected using a gas detector—a hydrogen leak detector, a helium leak detector, or the like. (3) Flow meter method Since the leak rate is equal to the flow rate, the leak rate can be measured by feeding air into the part under test through a micro flow meter.
