A DATA BANK OF PARAMETERS FOR THE ATTRACTIVE COEFFICIENT OF THE PENG-ROBINSON EQUATION OF STATE

A DATA BANK OF PARAMETERS FOR THE ATTRACTIVE COEFFICIENT OF THE PENG-ROBINSON EQUATION OF STATE

A data bank of parameters for two expressions for the temperature-dependence of the attractive coefficient, <FONT FACE="Symbol">a</font> (T), of the Peng-Robinson equation of state was compiled for 468 pure substances of varied polarity. The performances of the two expressions,...
