I'm interpreting your question to mean that (1) there is the same amount of
water in the tank, but (2) the water has further to go.
In that case, the depth function changes. Assuming there are h linear units
of water in the tank, you would still integrate from 0 to h; but more work
would have to be done on each "slice" of water, and that comes out in the
depth function.
This is a good question. Let me know if you have more.
