Hey Al, Its my turn to be a smart-***.
>If I punch a hole the size of my fist in the tank, more
>water will flow per second, but it won't be under so much pressure
Initially the pressure will be the same for both holes, as they would
presumably be at the same depth from the surface of the water, the pressure
will reduce faster for the larger hole.
Sometimes water analogies can turn to rubbish, but like you said, if it gets
some work done....
