It doesn't take work to life the water over the 3 foot wall of the cylinder? ![Wink](/tfp/images/smilies/wink.gif)

Not if you set up a siphon, no. But I guess "work" here refers to getting all the water up to the exit... by the way, how does a pipe enter something one foot above it? Also, my old thermodynamics professor would tear you apart for not giving units, like F=9.8*1000 of what? Newton? Pounds per cubic foot?
At every lecture he'd mock some poor student who had made a stupid error on one of his exams. We all lived in mortal fear of becoming one of his examples.
