• A cylindrical vessel, in which a tube is installed vertically in its base, is mounted in a reservoir. When heavy fluid is placed in the cylindrical vessel and light fluid in the reservoir, at first, the downflow of heavy fluid and the upflow of light fluid through the tube take place. This oscillation is repeated, and this system is called a density oscillator. In our research study, saltwater and fresh water are used as heavy and light fluids respectively. A theory based on the Hagen–Poiseuille flow approximation in a tube is constructed on the basis of the mechanism of the rise and fall of the saltwater surface. Our theory agrees well with experimental data. It is confirmed experimentally that the mean velocities of saltwater and fresh water in the tube immediately before the fall of the saltwater and the rise of the fresh water begin, are proportional to the density difference between saltwater and fresh water and inversely proportional to saltwater viscosity.
