Witryna1 lut 1972 · 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 … WitrynaCommon laboratory gravimetric procedures for determining density are the buoyancy technique, the displacement principle and the pycnometer method. The most widely used method is the buoyancy technique which utilizes Archimedes' principle: a body immersed in fluid indicates an apparent loss in weight equal to the weight of the fluid …
