| 内容記述 | Measurements of the viscosities of nitrogen, 80.4% N_2-19.6%H_2 System and 31.9%N_2-68.1%H_2 System have been made within the error of about 1 per cent, using the modified oscillating disc method, at the following conditions : namely, pure nitrogen at 25°, 100° and 150℃ up to 200 atm, 80.4% N_2-19.6%H_2 system at 50° and 100℃ up to 200 atm, and 31.9%N_2-68.1%H_2 system at 50℃ up to 200 atm and at 100℃ up to 100 atm. From these measurements it was found that (∂η/∂θ)_p is positive while (∂η/∂p)_θ becomes progressively smaller as the temperature increases and that (∂η/∂θ)_p is positive, remains constant over the whole density ranges within the limits of the experimental accuracy and is the function of the temperature alone. The experimental equations for viscosity-density isotherms were derived using the measured values. These equations reproduce them within the experimental accuracy. Calculating from the measured values, it was found that the deviations (〓_<(η)>) of the viscosities of binary mixtures (η_m) from those (n_Nη_N+n_H_ηH) made equal to the molal average of the viscosities of the components of the mixture are independent of the pressure within the experimental accuracv over the whole measured ranges and are the function of the temperature and the concentration ratio of components. | |||||||
