Taylor法による気体の相互拡散係数の測定 : 第3報, HCFC22-空気系の測定

抄録

The mutual diffusion coefficient of the HCFC22-air system has been measured at 0-180°C and at atmospheric pressure by the Taylor method. The experimental uncertainty was estimated to be ±2%. The present results can be represented by the following equation : D=7. 47×10^-10T^{1. 70}, where D is the mutual diffusion coefficient in m²/s and T is the temperature in K. The mutual diffusion coefficient of the Ne-Ar system has also been measured at 30°C for checking the reliability of the present apparatus.
