| Abstract: | An experimental study was made of the flow of the gases He, Ne, Ar, Kr, Xe, H2, D2, N2, CO2, and CH4 in the range of Knudsen numbers of 104–10?1 at room temperature in a capillary screen. A study was also made of the flow of a number of inert and diatomic gases at temperatures of 77.2 and 194.7 °K in an orifice and in a capillary screen. The relative flow rates were determined in the free-molecular mode of flow. The coefficients of accomodation of tangential momentum are calculated for the gases studied at different temperatures. |
