Abstract
The flow of inert gases, hydrogen, and deuterium was studied in a plane-parallel aperture ∼19 μ high formed by glass plates. A minimum volume flow rate is observed at a Knudsen number of ∼ 1. For Kn > 1, the volume flow rate increases without limit in the pressure range studied. The experimental results for the different gases differ greatly in the region of free molecular flow. Neon displays a behavior different from that of the other gases. The available theoretical results are compared with the experimental results.
