The physics of water turbines
A water turbine converts the potential and kinetic energy of water to rotational energy. This module describes the designs of water turbines. It briefly refers to the principles of fluid mechanics.
Information and ideas:
What is the reason for the different designs of water and gas turbines? How do the working media (water or gas) differ in terms of their physical properties? What does the Bernoulli equation have to do with the spoiler on a racecar or with an airplane?
Interdisciplinary lessons in geography and technology: Students learn to determine which types of turbines need to be used on the basis of the geography of selected hydroelectric plants.
The images on the first page of the information module show museum objects, so the turbines are not technologically up-to-date. However, the differences are easy to recognize.
