Jinnyeol, for part two, the shape of the graph will look like that of y = ln x or the bottom right quadrant of the graph of y = -1/x, except that the graph starts from (0, 0) since the container is initially empty and the water level at the start is zero.

This is because the same volume of water fills up a “larger water cross sectional area”, hence slowing down the rate of increase of the height.
