The educational unit is designed to demonstrate cavitation (FM – 017) processes and formation of vapor bubbles in a Venturi nozzle
- The educational unit is a vertical panel to be fixed at the top of the main hydraulic unit.
- The educational unit is supplied with a thermometer, a rotameter, a gate valves for flow adjustment, a pressure reducing valve, a Venturi nozzle and manometer.
- Through the educational unit, the pressure energy of water is converted into kinetic energy and vice versa in the Venturi nozzle. Therefore, vapor bubbles form in the narrowest cross section.
- The Venturi nozzle is made of transparent plastic to allow visualizing of the flow processes.
- There are three pressure measuring points on the Venturi nozzle: at the inlet, at the narrowest point and at the outlet.
- The flow rate and the pressures can be controlled by two ball valves which are located at the inlet and outlet of the pipe system.
- The flow can be read off a rotameter.
- The pressure distribution within the Venturi nozzle is displayed on three manometers.
- The temperature is measured directly upstream of the Venturi nozzle and is shown on the thermometer.
- The input pressure can be controlled using a pressure reducing valve.
