Since a rigorous microscopic treatment of a nematic fluid system based on apairwise interaction potential is immensely complex we had introduced a simplemean field potential which was a modification of the Maier-Saupe potential in aprevious paper. Building up on that here we have modified that potential totake into account the various aspects of a smectic A-nematic phase transition.In particular we have studied the dependence of the phase transition on thecoupling coefficient between the nematic and smectic order parameters which inturn depends on the length of alkyl chain, existence of tricritical point,variation of entropy and specific heat as well as the dependence of the phasetransition on pressure.
