Water presure

  1. Oct 21, 2011 #1
    Hi

    Can someone please confirm me on this one

    1. Is this picture correct? (The water level in the big tank and in the pipe will be the same)
    2. Water level in big tank and pipe would be the same regardless of pipe size (red)

    Thanks

    You are correct.

    yes, the water level will be equal if the external (air?) pressures are equal.

    If this is so, the P= hd of the water must be equal on each side, otherwise there will be a pressure differential between the two sides and that will cause water to flow.
