The pressure curves of fluids in motion and fluids at rest in pipes are fundamentally different from one another. For the same supply pressure, losses occur in flowing fluids due to the pipe friction; these losses manifest themselves as pressure losses. In fluids at rest the static pressure in horizontal pipe elements is constant. It visualises the pressure curve of flowing and static incompressible fluids in pipes. The trainer is suitable for explaining concepts such as the hydrostatic pressure in static and moving liquids. The clear panel is mounted on a sturdy, movable frame. The supply pressure is generated by an elevated tank. In order to ensure a constant supply pressure, the tank is fitted with a refill mechanism and an overflow. A measuring section is located at the end of the tank. The flow and thus the flow velocity can be adjusted at two points. There are six pressure measuring points along the measuring section. The respective pressures can be read via the tube manometer with reference to the height of the liquid column.
