Technical data How heating is influenced by the position of the absorber in the parabolic troughItem No. P9519200 Principle This experiment shows how great the effect of exact alignment of the test tube and the parabolic trough is on the heating of the water. Even a small focal point offset results in distinctly weaker heating. This principle is also used in solar cookers for food. In this case, the pot must be at the focal point of the reflector for high efficiency and so rapid heating. The influence of the exact positioning of an absorber in a parabolic trough is to be clearly shown in this experiment. A temperature measurement series is to be carried out in each of the two parts and a comparison then be made. Benefits
Tasks Is the position of the test tube in the parabolic trough important?
