Abstract: | <p> A series capillary viscometer has been used to measure the viscosity of nitrogen and air over a temperature range of 100 to 400°K and to pressures of 150 atmospheres. </p> <p>The low pressure results have been correlated using a modified Sutherland equation of the form: n = C1T^C2 / T+C3 </p> <p> Intermolecular force constants have been computed for nitrogen using the Chapman Enskog collision theory approach.</p> <p> The viscosity in the dense gas region was correlated using equations of the form n-no = A1ρ + A2ρ^2 and thus overall equations for viscosity as a function of temperature and density were formulated as n = C1T^C2 / T+C3 +A1ρ + A2ρ^2 </p> <p> These equations were used to generate tables of smoothed values of viscosity as a function of pressure and temperature.</p> |
