It is known that the presence of liquids can significantly affect the dynamic motions of immersed solids. This paper proposes a method for evaluating fluid forces for use in the dynamic analysis of moving systems in which solid bodies are completely immersed in incompressible, frictionless fluids. A damping parameter is suggested to determine whether a fluid system may be considered frictionless. The incompressibility requirement is also discussed. Experimental data are cited to support the proposed method. Formulas for hydrodynamic masses are tabulated.
