Research Abstract	Fluid equation describes space-time evolutions of systems of liquids and gasses such as water. Especially it works well when, e. g., the number and energy densities of the systems vary moderately. The fluid equation possesses some input parameters, which can, in principle, be calculated from microscopic Lagrangian. In our study we tried to build up a renormalization flow equation for evaluating these parameters systematically as functions of, e. g., temperature and density in the whole region of the phase diagram including critical or transition points.
