Product Details

Technical Description
The hydrodynamic trainer HM 110 permits basic experiments on fluid mechanics. The experiment is set up clearly on a mobile laboratory trolley. Thanks to the closed water circuit the test stand is especially well suited for use in seminars and lecture rooms. The system includes a variable-area flowmeter, an electronic differential pressure gauge and other pressure measuring devices. The objects to be measured are various pipelines and add-on parts, five of which represent different types of pipe installations (such as a membrane valve or dirt trap). In order to make the function of the unit visible, three of the objects are made of Plexiglas: they represent a Venturi tube, pitot tube and measuring orifice/nozzle. The measuring points and pressure gauges are connected with hoses and rapid action hose couplings

Learning Objectives / Experiments
· Measurement of pressure and speed with the pitot tube
· Measurement of flow rate with nozzle and orifice
· Investigations at the fittings: Comparative measurement of pressure loss, head loss and flow rate in relation to the degree of opening
· Investigations at the pipelines: Pipe flow with and without friction, narrowing and widening of pipe, angles and bends
