    Today i accidentally fell into a pipe of water of approx 500mm, and luckily only got wet to chest height but the pipe was much deeper. Maybe 6 or 7 meters.
    I was glad how quick i got out and i thought i was possibly more buoyant in a pipe compared to a larger body of water.
    Could this be true, or was it just my hurry to get out.
    I don't wish to do a physical experiment, so a theory based answer would suffice!

    Water density depends only on temperature, but the effect is generally small.

    so you don't think that the high displacement of the water in the pipe would make a difference?
