Fluid MechanicsProperties Of Fluids And Hydrostatics Bench
With this well equipped hydrostatics bench, numerous experiments on the topic of the hydrostatics of liquids and gases can be carried out. A pipe section and various pressure measuring devices are fitted to a laboratory trolley with a demonstration panel, working area and cabinet. Various measuring containers are integrated into the pipe section. The sealed water circuit and pump with supply tank permit experiments to be performed independent of a mains water connection. This feature makes the bench particularly suitable for use in seminars rooms and lecture theatres. Further experimental apparatus are included in the cabinet, e.g. a device for determining the centre of pressure of a column of water. This enables the pressure on a weir to be determined, amongst other aspects.

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.

Stability Of A Floating Body
This simple apparatus for determining the metacentre of a model hull is particularly suitable for experiments in small groups. The experiments are performed in a tank filled with water. A transparent hull is used with a rectangular cross-section. Horizontal and vertical sliding weights enable the center of gravity to be adjusted. The position of the sliding weights as well as the draught of the floating body can be read on scales. An inclinometer indicates the angle of heel.

Thermal Engineering Equipments
The demonstrator is designed such that it can be set up with an inlet tank and an outlet tank .The inlet and outlet tanks guarantee constant-pressure conditions. A flow channel of variable cross-section and transparent viewing window forms the main component of the experimental set-up. By means of the addition of ink, the velocity along the channel can be demonstrated. A twelve-tube manometer for measuring static pressure is distributed along the length of the nozzle at even distances to indicate the pressure distribution.

Twin Centrifugal Pump Configurations
The system comprises 2 identical centrifugal pumps that are connected together via pipes. Manual valves make it possible to switch quickly between series and parallel operation. Manometers indicate the pressure at all important points in the pipe system. The pump characteristics can be recorded. The hydraulic power output of the pumps can be determined. The water supply and volumetric flow rate measurement are provided by . Alternatively, the arrangement can also be operated from the laboratory mains supply.
