Add to ORKGThe allowable leakage rate for space hardware is typically specified as 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 U.S. Spacesuit Knowledge Capture seminar, Dr. Eugene Ungar will explore the physical configuration of typical leak paths, discuss the physics of molecular, transition, and continuum flow, and present the accepted method of conservatively calculating the expected leakage rate of the working fluid
