Leakage Correlation from Helium to Working Fluid

The allowable leakage rate for space hardware is typically specified as standard cubic centimeters/second (scc/sec) of helium. It is important to be able to use the measured helium leakage rate to calculate the expected leakage rate of the working fluid. In this seminar, Dr. Eugene Ungar explored the physical configuration of typical leak paths, discussed the physics of molecular, transition, and continuum flow, and presented the accepted method of conservatively calculating the expected leakage rate of the working fluid.
