  • Descrição: 気体R-12の粘性率を振動円板粘性率計により温度298.15~398.15K, 最高圧力4.1MPaまでの範囲で測定した.常圧における実測粘性率を温度の関数として実験式を定めた.またLennard-Jones 12-6ポテンシャルの分子間力定数を次のように定めた : ε/k=215.9K, σ=0.5496nm.
    Viscosity of gaseous R-12 was measured using a oscillating disk viscometer of Maxwell type at 298.15398.15 K in the pressure range up to 4.1 MPa. An empirical equation was obtained to represent the viscosity at normal pressure as a function of temperature. Force constants for Lennard-Jones 12-6 potential were determined from the observed viscosity values at normal pressure as follows : ε/k=215.9 K, σ = 0.5496nm.
