It is well known that the shape of liquid drop on flat surface is dependent to several energy. One of these energy is surface energy. In this paper to attempt calculate the Free energy of liquid drop on the flat surface and then with extermomize of it, suggest a method for measure surface tension or contact liquid angle with flat surface.
