Abstract
Based on nitrogen sound speeds measured by Younglove and McCarty in 19 80 [J. Chem. Thermodynam. 12, 1121-1128 (1980)], a multicolumn coeffic ient fitting method is used to derive an empirical equation for the co mputation of sound speed at temperatures from 150 to 330 K and pressur es from 0.028 75 to 1.506 85 MPa. The maximum deviation between the me asured sound speeds and those computed with the empirical equation is less than 380 ppm.
