Prediction of compressibility fac tor of Argon fluid with hard-core sq uare-w ell potential at different thermodynamic states

The thermodynam ic properties of a f luid can be obtained from the radial distribution potenti al of arises from the fact that, given the form of the functio n . The importanceof the intermolecular force, if the is known as a func tion of and the temper ature T, the standard methods of statistical mechanics allow for th e determination of all the equilibrium properties of the flui d. The usual approach to obtain is through one of the integral equation theories [۲]. Thermodynamic property ell (SW) fluids has of square-wbeen a subject of interest for many years because of their simplicity and their resemblance to real fluids with sp herically symmetrical p otentials, among othe r reasons. Therefore, at present there ar e available a considerable numb er of theories for this kind of fluid [۱]. In this work, we app lied SW p otential for calculati ng compre ssibility fa ctor of Ar gon fluid u sing an expression for in an integral equatio n approach .
