Swimming Pool Physics

    Right so, I need something explained to me. Swimming pool air temperature must be one degree above water temperature so as to prevent damage from condensation forming on pipes and other stuff around the pool.

    Anyway, I don't really get how this works. I would hazard a guess that humidity plays its part but I just need someone to explain how this temperature difference prevents evaporation and condensation.

    Hope my question is clear! Thanks

    Condensation forms when hot air hits a cooler surface. As the air cools it can't hold as much water vapour so deposits some on the surface. If the air temperature was less then the water temp then the water would heat the air just above it, which would also collect some water vapour. When this air hit the pipes it would cool and deposit water vapour. By keeping the air temp slightly above the water temp it means the air will all largely be the same temp so the humid air won't suddenly hit a cooler surface.

    (or something like that anyway)
