Mechanics of flow

Principle

The ultrasonic Doppler effect is used for studying the laws of steadily and laminarly flowing liquids in a tube circuit, which form the basis of numerous technical applications. The experiment focuses particularly on the relationship between the flow velocity and the cross-sectional ...

Water quality - contamination with heavy metals

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanic or similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may ...

Detection of quinine in tonic water

Principle

Chinine is the main alkaloid of the bark of the Chinabaum. It has a typical, bitter taste and is hardly soluble in water, but soluble in alcohol, ether and chloroform

In this experiment, chinine is extracted from tonic water with an organic solvent and detected by its fluorescence ...

Electrostatic flue gas cleaning



Principle

Smoke consists of particles of solid substances suspended in gas. Fog is made up of suspended droplets. In cigarette smoke, as in many industrial processes, smoke and fog are frequently present together. The removal of particles contained in gases - predominately waste ...

Model experiment on the desulphurisation of flue gas

Principle

German coal contains an average of one tonne of sulphur per 100 tons of coal. The combustion of this 100 tons of coal "produces" about two tonnes of sulphur dioxide. In comparison a large 700 megawatt power plant which burns about 200 tons of coal per hour produces ...

The current-voltage characteristic of a solar cell

Principle

A solar cell is to be subjected to various loads, to investigate how the current and the voltage behave with respect to each other, and to determine under which load the solar cell generates its maximum power.

Series and parallel connection of solar cells - open-circuit voltage and short-circuit current

Principle

Series or parallel connection of solar cells can be used to change voltage and current and to adjust them to the consumer's needs. The short-circuit current of solar cells is proportional to the irradiance, while their voltage output is nearly independent of it.

Benefits

  • No ...
