Here's an extra problem you can practice on. NOTE: the solution assumes the bottom of the tank can move, compressing the air inside, which was not clear from the problem statement. Hence, the answers are different here than your solutions. When tank has a fixed bottom, e.g., fixed volume, then h = 1.27 ft for (a) and F = 337 lbf for (b) ...
