Comparison of bulk modulus as Benzene dense fluid using the perturbation theory and comparison with Peng-Robinson equation of state

The bulk modulus, is a scalar quantity relating an isotropic pressure to an average change in volume. It is the average of the three inverse li near compressibilities (change of length induced by pressure). Huang and O’Connell [۱] checked the regularity for more than ۲۵۰ fluids and used it as the basis of a correlation scheme for the volum etric properties of compressed liquids and liquid mixtures. Boushehri [۲] presented a theoretical basis for this regularity interms of a statistical–mechanical equation of state [۳]. Linearity of bulk modulus as a fu nction of pressure: More than ۱۰۰ years ago, a regularity has been discovered by Tait [۴] in which isotherms of bulk modulus (reciprocal isothermal compressibility),(...)of a liquid as a function of pressure vary linearly.
