Tube Radius and water height

  1. Jul 28, 2006 #1
    if i put two pipes in atank of some liquid and fill it up, will the height of the liquid be different in the pipes if the radios will be different?
    if not how can i create asituation so the height of the liquid will be different?

    I think the OP means "radius" or "radii".

    Yes, the height of rise is a function (it varies inversely) of the radius of the pipe. However, note that there will be no noticeable rise if the radius is more than a centimeter or so, for a typical liquid. To see a significant height difference you should use capillary tubes (not pipes) with radii that are in the mm range.

    thanks you were right it was radius:)

    I think he means "televisions"

    [Assuming I understand your question...] You can't. Pressure is what determines the height of the water in the two pipes. As long as they are connected to a static system, they will have the same pressure at the same height - ie, exactly the same as the height of the water in the tank next to them.
