AbstractGeneral equations for the temperature dependence of the parameters of the Hudleston equation are given which were deduced from a study ofn‐alkane compression data. Empirical expressions for the molecular‐weight dependence of the constants of these equations are likewise given which are applicable only ton‐alkanes. By use of these relations in the Hudleston equation the compressions of the family of liquidn‐alkanes over ranges ofT, P, andmwere calculated on an IBM‐650 computer. The over‐all standard percentage error (SPE) of the computer calculations forn‐alkanes of 7 to 20 carbons up to temperatures not exceeding their normal boiling points was 0.10%. The over‐all SPE forn‐alkanes of 7 to 40 carbons up to temperatures substantially above their normal boiling points (but not exceeding

摘要:

AbstractA study was made of the deviation between the temperature of thermocouple junctions and the temperature of the fluid surrounding them which arises as a result of conduction along the thermocouple leads. Measurements around a 1/2‐in. heated sphere in the plane of the equator normal to an air stream having a velocity of 16 ft./sec. were made with a 0.001‐in.‐diam. thermocouple of platinum and platinum rhodium. Air temperatures in the boundary flows of the sphere were predicted from the indications of the thermocouple. The method of prediction employed also determined the heat transfer coefficients for the thermocouple wire in the boundary layer. These local heat transfer coefficients are lower than those observed in a uniform stream having a velocity equal to the estimated local velocity in the boundary

摘要:

AbstractIn 1954 Becker found that the components of a gas mixture could be separated by allowing a jet of the gas mixture to expand in a low‐pressure chamber. The heavier molecules would concentrate near the center of the jet and the lighter ones near the edge. Thus the jet could be split into two streams, one containing more of the heavy component and one containing more of the light component. In this paper it will be shown that this effect can be predicted from the kinetic theory of gases and that the predicted magnitude of the effect agrees favorably with the experimental data of Becke
