A container contains 10L of water. There is a tube attached to the bottom of it that has a diameter of 3cm and it is at a height of 1.5m. The container has two openings, one on the bottom, where the water can get out, and a opening at the top, where air pressure will be going through in order to raise the water in the tube. If the container has a volume of 18L in total, how much air pressure must be pressured into the container in order for the water to raise to the top of the tube?

what ever the pressure water wouldnt raise to the top .. if u could make the question more clear i can answer :)..just put up a figure :)

As I see it, air pressure will have to be just as much as the water's mass times gravity weighting at the bottom of the tube. Since the water force (weight) downward will be opposed by air in the same tube diameter, then this tube diameter is the surface where the pressure acts. Remember, pressure can be in Newtons/square meters = Pascals.

Ahh, mass of water is 1Kg per liter. If there is a picture of the experiment, you can draw it using the blue DRAW bottom, it would clarify a lot as to what to account for the mass of water to include in the equation.
