    and
    if those tanks do not have lids, only 4 will be filled.

    I thought I had the answer bookmarked but cannot find it now.
    I'm thinking 3 for now. If not then 3 & 4. A short search found 3 different answers : 3, 4 & both 3 & 4.
    I am certain it cannot be 1 or 2 or both.
    I will be searching more.

    3

    Water will flow into

    2 and straight out into

    3 and rise up to outlet pipe leading to

    4 when it will begin to flow into

    4

    The water flowing from

    3 to

    4 will be replaced by the incoming water from

    2 keeping

    3 full

    Very close to what I was thinking. Also that it takes more pressure to force water up than straight across thus 3 must be fuller than 4 & will be full just before 4 is.

    Anyone else?

    Once the flow from

    3 reaches the overflow into

    4 the water flow effectively becomes a direct flow from

    2 into

    4

    As a sub question

    The pressure from 3 is pushing water up connecting tube to 4

    Once water begins to flow into 4 does the water going across the level tube

    Drop in pressure?

    Remains at same pressure?

    Increase in pressure?

    My thinking is drop but I am by no means certain

    I need to copy this to a document to answer at this point. I would not want this to happen much but maybe it is good I lost the solution. This is interesting.

    (Damn. I meant to reply to your post.)

    With the tank question, water will rise up in tank 3 until it is level with the inlet to tank 4, and tank 4 will only start filling after that. So if tank 3 is considered "full" when the water is at the level of the inlet to tank 4, then tank 3 will definitely fill first. While 3 is filling, water will be running from 1 to 2 to 3, so that 1 and 2 won't fill up.

    Also, if tank 4 is open at the top, then 1 and 2 will never fill up unless the flow rate from the input tap is very high.

    A computer keyboard?

    Usually I'm not very good at these kinds of things, but I seem to be on a bit of a roll here...
