  Principles of Hydraulics

  The is part of a series of units that enable experiments to be performed on flow processes with the aid of a computer. Here several areas of incompressible flows can be investigated. After the recording of a pump characteristic curve, experiments on the topics of pipe flow and flow in open flumes can be performed. Water flows through a Venturi tube, an orifice, a bend, or a kink. During this process the pressure loss is measured and compared with the flow through a straight pipe. On flumes experiments can be performed on the open channel and on a channel with weir structures. Two different weir structures are supplied . The Data Logging Unit is necessary for the operation of the Computer Linked Hydraulics Bench. If power data is to be displayed, the Digital Power Meter is required.

  Sediment Transport Demonstration Channel

  Some Practical Possibilities of the Unit: Flow over a mobile sand-bed (bedforms associated with increasing flow intensity and sediment transport rate) 1.- Lower Regime (bedforms exhibed): – Plane- bed (no motion). – Washed-out dunes. -Ripples. -Dunes. 2.- Upper Regime(bedforms exhibed): Plane- bed (with motion).3.- Although the channel can not transport gravel, this can be used to investigate flow resistance in gravel and polder- bed rivers. 4.- We can calculate the flow resistance coeficients, using equations such as those of Bray, Limerinos, Hey, Lacey, Thompson and Campbell and Bathurst and the results compared to the actual values obtained by observation. 5.- We can examine the structure of turbulence in the flow, using dye injection, interesting for the dune bedform configuration and clearly demonstrates separation on the lee face. 6.- Rapid, super- critical flow- dominance of intertial over gravity forces, shock waves from flow obstructions.

  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.
