The unit is designed to be used on Hydraulics Bench which allows the volumetric measuring tank to be used for flow measurement. Alternatively the unit can be used on a laboratory bench with water supplied from a tap and with the unit discharging to a drain. Osborne Reynolds Unit comprises a reentrant bell mouthed glass experimental tube of 16 mm bore and approximately 650 mm long mounted horizontally in a 103 mm bore perspex tube. Flow control is achieved by an angled seat valve at exit from the apparatus. A dye injector probe and adjustable head dye reservoir are provided to introduce a dye filament for the observation of laminar, and turbulent flow regimes, and the transition between them. An adjustable height constant head inlet tank supplies water to the annulus so that the water flows along the annulus through a baffle into a reverse flow stilling chamber, thus providing a uniform flow with very little turbulence into the bell mouth entry of the experimental tube.
Experimental Capability:
Determination of the lower and upper Critical Velocities and Reynolds Number.
Demonstration of laminar or streamline flow, turbulent flow and the transition between these two regimes by observation of injected dye line.
A throttle valve makes it possible to regulate the water flow rate. A series of park-away threaded holes along the bottom of the channel (spaced 250 mm apart) allows to fit the optional models. A guide is assembled on the sides of the channel to carry the accessories and the instruments necessary for the tests. The bottom of the channel can be tilted by up to 1.5 degrees, so as to simulate the normal inclinations of the real channels; it is also possible to obtain a slight negative slope. The centrifugal pump draws the water from the collection tank and transfers it to the still tank, where a manually operated vertical gate, which is assembled before the testing section, allows to vary the height of the hydraulic load. The unit is supplied with manuals that describe each component of the system, installation and utilization procedures, and gives many exercises.
The series of channels has been designed by to study the hydrodynamic phenomena of the open surface streams in variable inclination channels. The following versions are available:
Open Surface Tilting Flow Channel 5 m long
Open Surface Tilting Flow Channel 3 m long

The duct work includes flow straighteners and an adjustable discharge valve. A tangential fan (i.e. fitted with a narrow chord centrifugal impellor), directly driven from a single phase induction motor, provides the necessary air flow for experiments. The fan is capable of providing a flow of 500 litres/second at a static pressure rise of 800 Pascals. The instrumentation supplied with the Air Flow Bench comprises a digital manometer, barometer, conical inlet flow measuring device, and pitot static tube for traversing the duct. An electrical enclosure is mounted on the upper work surface and contains the fan contactor, fan start and stop pushbuttons, and provides electrical power for optional additional equipment. An optional data logging system with various modules is available to provide 0-10V dc analogue outputs of all measurements for interfacing to a computer system.

Balances can be divided into two main groups: internal and external. The group names are derived from their location relative to the test model and wind tunnel test section internal balances reside inside a test model, while external balances reside outside the test section. During the early years of wind tunnel testing, Forces and Moments were literally measured through pan-type balances. Internal Force/Moment balances are almost universally used for measurements in supersonic and transonic tunnels. However, they are also becoming popular in subsonic tunnels. Although technology has advanced dramatically since those early days, the term balance is still applied to the devices used for Force and Moment measurements today.

Steam passes from the inlet chamber, through the test nozzle, into the exhaust chamber and finally into the surface condenser via a back pressure control valve. Nozzle Steam Bench consists of a sturdy framework and panels of all steel construction, fitted with a student work surface, interconnecting back panel and adjustable feet. Steam supply to the inlet chamber first passes through a steam separator to remove excess water content and the chamber is fitted with a throttling facility to enable the dryness of the inlet steam to be determined. The steam chest consists of an inlet chamber and an exhaust chamber with a test nozzle positioned in the wall common to the two chambers.

The model simulates a helicopter with horizontal and tail rotors to give pitch and yaw control. The control system must keep the helicopter stable and allow for a change in the centre of gravity. When operating near the steady state, the electromechanical system can be linearized to a six-order model. Sensors measure the yaw and pitch angles. This gives a two-input and two output system, with cross-coupling. Students use the educational manual (supplied) to help identify plant dynamics and create a control system.

Geothermal Turbine Trainer has multiple gauges for DC power (voltage and current) and several outputs for harnessing the electricity produced. Pressure relief and controls are mounted for safety. This system simulates an electric power generating plant, which uses a steam turbine.
The Geothermal Trainer shows students how thermal energy is used to generate electricity via a turbine, just as production wells use this source in geothermal power plants. Geothermal energy is a renewable and sustainable power source that comes from heat generated by the earth.
The amount of power generated is controlled by boiler pressure and/or the amount of fuel burned under the boiler. The student will burn pro-pane fuel or natural gas to generate steam, which is injected into a transparent turbine coupled to an electric generator, producing electricity.
