A lighting unit simulates natural solar radiation and allows a range of experiments to be carried out in the laboratory. The light is converted into heat in an absorber and transferred to a heat transfer fluid. Solar thermal systems convert solar energy into usable thermal energy. It allows you to demonstrate solar thermal heating of domestic water in an illustrative manner. The heat is released to the water by an integrated heat exchanger in the tank. A pump conveys the heat transfer fluid through a hot water tank.

Reversible Pendulum Apparatus can be suspended from either pivot and swung. The two pivots are adjustable on the rigid metal bar and this allows the periods of swing to be adjustable. The Reversible Pendulum Apparatus consists of a rigid metal bar with two pivot points, one near each end of the bar.
The movable pivot is adjusted until the two periods are equal. From the period and the measured distance between the pivots, the acceleration of gravity can be calculated with great precision. In use, it is swung from one pivot, and the period timed, and then turned upside down and swung from the other pivot, and the period timed. At this point the period is equal to the period of an ideal simple pendulum of length equal to the distance between the pivots.
Experimental Capabilities:
To find the acceleration due to gravity 'g'
Investigate the effect of fulcrum position.
A small microphone may be moved axially along the tube and Acoustic Impedence Tube position measured. The loudspeakers are fed with a common pure tone from a function generator and the sound waves pass along the tube to the sample. The Acoustic Impedence Tube consists of a transparent plastic tube fitted at one end with a glass reinforced plastic enclosure containing two loudspeakers and at the other with a heavy sample holder. The portion absorbed being converted into heat by the viscous action of the airborne wave as Acoustic Impedence Tube passes through the absorber. Dependent upon the type of material and the tone frequency, a portion of the sound energy is absorbed and the remainder is reflected back along the tube.

Two Phase Flow occurs when a gas is flowing in a confined space with a liquid. The flow profile and geometry in this instance varies widely as a function of the liquid and gas material properties as well as the flow rates through the pipeline. The Two Phase Flow Demonstrator apparatus is a small scale flow loop that can demonstrate Two Phase Flow phenomena in pipes at a variety of liquid and gas flow rates. It is important that the process operator understand the basics of Two Phase Flow Demonstrator in pipelines, especially as it pertains to the formation of the destructive slug flow regime. Certain flow regimes can be destructive to facility piping, and should be avoided where possible. The destructive effects of these flow regimes can be managed through the use of various piping geometries.
The air and water flow rates are continuously variable over a wide range of flow rates. This allows the operator to observe a wide range of two-phase flow regimes using this demonstrator. The Two Phase Flow Demonstrator is mounted on a movable cart for ease of movement and storage. Two Phase Flow Demonstrator uses air and water to create different flow regimes in the process piping. Air is supplied to the system by a low pressure blower, and water is supplied through a centrifugal pump.

The micro-organisms utilize the contaminated substances as necessary food for their production and their preservation. The aspect for this mass of micro-organisms is that of sludge, from which we have taken the name of the process. The activated sludge pilot allows the study and the comprehension of sewage treatment by activated sludge. This Activated Sludge Sewage Treatment Pilot Plant is an intermediate stage between the physical treatments or grid iron, and primary sedimentation and the final sterilization and chlorination stage, in a sewage treatment station. The conditioning process takes place in a tank where the organic load is removed by microorganism which are cultivated under aerobic conditions by blowing in air or sometimes also pure oxygen. After the pollutant elimination phase it is necessary to divide the clarified water from the sludge, operation which is carried out in the settling tank (stating separator). Its purpose is to eliminate the contaminated organic substances which are present in the sewage water after the above mentioned physical treatment. The organic load is measured in BOD (Biological Oxygen Demand) unit and it also causes a partial elimination of COD (Chemical Oxygen Demand).
