    The problem just asks how to transfer the water, right?
    Frankly "turn on the pump" is jumping up and down and waving at me...
    Is there a part b? Like, complete part a, and find some value?

    Or build a http://en.wikipedia.org/wiki/Siphon" [Broken]. :smile:

    Why do either of those things? The problem is to transfer water from the upper tank to the lower. I would assume that the pump would be there to go the other way. Answer- open the valves!

    I guess it's a perfectly valid question if two out of three PF members got it wrong!

    1] If the pump were turned on, the valves would still be closed.
    2] We don't know which way the pump pumps.

    Answer - as HoI points out: open the valves!

    Hm. It does specifically say both tanks are sealed. Without backflow of air, it would take a very long time to transfer.
    Turning the pump on would speed the process.

    Open the valves and punch holes in both tank tops.
