The apparatus consists of a self-contained bench complete with all necessary equipment for a wide range of demonstrations and experiments in hydrostatics and properties of fluids. The bench has a reservoir that supplies water for the experiments. A tank on the unit can be filled from the reservoir for experiments that need a free-water surface. Much of the equipment is rigidly mounted on the bench, the remainder being free-standing items suitable for use on the bench top. The bench is readily movable and is therefore ideal for lecture room demonstrations as well as student experiments. A toroidal sloped tank is mounted within an integrated balance to determine centre of pressure. Experimental equipment supplied with the bench includes a fluid-level apparatus for demonstrating Pascal’s law, and two U-tube manometers.
