## Abstract Apparatus is described for experimentally determining diffusion coefficients in denseβgas systems to pressures of 15,000 lb./sq. in. abs. Tests were made with the hydrogenβnitrogen and methaneβethane systems at 104Β°, 139Β°, and 171Β°F. to 10,000 lb./sq. in. abs. and with the nitrogenβmeth
The effect on the ordinary coefficient of diffusion of the mobilities of two interdiffusing, non-ionic components is evaluated by a straightforward application of the equations of irreversible thermodynamics along the lines suggested by DE GROOT [l]. The form of the resultant equations for the diffu
