  Computer Controlled Water Tunnel

  Water tunnel of 500*500mm, principal characteristics: * Adequate Size for flow visualizations on standard models of planes. * Useful for teaching and development projects. * Top quality vein, uniformity and low turbulence level. * Low operation and maintenance cost. *The water tunnel of 500*500 mm, of low turbulence level, is specifically designed for carrying out visualization tests on threedimensional models, though, of course, they can also be used on two-dimensional models. *As it is a closed circuit, it operates continuously and uses the same water, although it may be necessary to renew it once it has lost its transparency due to the use of colorings. However, if the technique of the hydrogen bubble is used as tracer this problem can also be avoided. *Its dimensions and low operating costs make it suitable for teaching as well as for research or industrial use. Assorted systems for registering images and taking measurements can be incorporated when necessary.

  Demonstration Pelton Turbine

  A characteristic of impulse turbines is the complete conversion of pressure into kinetic energy at the exit of the supply nozzle. The turbine consists of a housing, which is transparent on one side, the Pelton bucket wheel and an adjustable supply nozzle. The turbine is loaded with a belt brake. The torque is measured using spring balances located on the braking belt. The manometer fitted to the unit measures the water pressure applied. The pressurised water supply and flow rate measurement is provided . Alternatively, the arrangement can also be operated from the laboratory mains supply.

  Hydraulic Ram Pump

  Using this type of pump it is possible to pump water to a higher level without additional mechanical energy. During this process the kinetic energy of the water flowing in a long pipe is converted into potential energy by suddenly stopping the flow. A valve pulsed by the hydraulic force of the water makes the hydraulic ram cycle automatically. The function of the hydraulic ram can be clearly seen with unshrouded valves and transparent cylinders. The water hammer develops in a pipe loop. All components are mounted on a clearly laid out panel. The flow rate is adjusted using manual valves. The water supply is provided either from the laboratory.(closed water circuit).

  Hydrodynamics Trainer

  The hydrodynamic trainer 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

  Hydrodynamics Trainer / PC

  The trainer permits basic experiments on fluid mechanics. The experimental set-up is clearly laid out on a laboratory trolley. Due the use of a sealed water circuit, the trainer is particularly suitable for use in training and seminar rooms, and also lecture theaters. The system contains pressure and flow rate sensors that allow the values measured to be further processed on a PC. 6 different pipe sections and 8 components are used as measurement objects; of the 8 components, 5 represent components built into pipes, e.g. a membrane valve or dirt trap. 3 measurement objects are manufactured from Plexiglass and represent a venturi tube, a pitot tube, a metering orifice and a metering nozzle. With the PC data acquisition card and software included measured values can be displayed and evaluated on a PC.
