Abstract: In this paper, the simple method to find empirical formula using the experimented and researched data to be plotted on the coordinate paper of related function not to form a straight line is introduced. As examples, the relation curves plotted on log-paper, semi-log paper and ordinary coordinate paper in hydraulics and soil mechanics were selected. With these three typical curves the procedure of simple method to find empirical formula is stated . Consequently the formulas of drag coefficient for an immersed sphere body moving through water, settling velocity for silt and sand , settlement consolidation degree for soft foundation and storativity are obtained.
