I'd like to apply physics principles to a home-experiment relating to my swimming pool.
The water should flow inner to 100 meters of black pipe and so it should become warm. Then it should return in the swimming pool.
But how can I carry the water from the swimming pool to the pipe? if I use a tight pipe, for the capillarity and putting the pipe vertically from the bottom of the swimming pool, the water should come up.. but it has to pass about 30 cm... is it possible to pass a similar hight using capillarity? (the pipe should be 30 cm over the water level) Which should the pipe diameter be?
If the idea is impracticable, which principle can I use?
