Abstract

The Chakma-Lielmezs-Islam modification of the Martin equation of state {A figure is presented} where a(T)=a(P_c,T_c)α(T^*) in which {A figure is presented} α(T^*) = 1+pT^*q has been extended to unsaturated liquid and vapour states by means of a correcting function C_f, such that the α(T^*) term becomes α(T^*) = 1+pC_fT^*q The proposed extension has been successfully compared with the results obtained by means of the original Martin equation of state, the Chakma-Lielmezs-Islam modification of the Martin equation for the saturated states, and the Soave-1972 modification of the Redlich-Kwong equation of state.
