You are planning on installing a new above-ground swimming pool in your backyard. The pool will be rectangular with dimensions
32.0 m x 10.0 m. It will be filled with fresh water to a depth of 2.20 m. In order to provide the appropriate structural support, you
wish to determine the following.
(a) Determine the force exerted on the bottom of the pool by the water (in N).
(No Response) N
(b) Determine the force exerted on each end of the pool by the water (in N). (Assume the end is the 10.0 m wall.)
(No Response) N
(c) Determine the force exerted on each side of the pool by the water (in N). (Assume the side is the 32.0 m wall.)
(No Response) N
(d) You wish to have swimming parties with your children and grandchildren. At a given time, you might have 23 people with an
average mass of 75.0 kg in the pool. You need to determine if such parties will affect your calculations for the required
strength of materials supporting your pool.
The parties will not affect the required strength since…
The construction of a water pistol is shown in the figure below. The cylinder with cross-sectional area A₁ is filled with water and

cylinder and tube are, respectively, 1.30 cm and 1.10 mm, and the center of the tube is a height h = 3.00 cm above the center of
the cylinder. (Assume atmospheric pressure is 1.013 × 105 Pa.)

- = = You are preparing your house for a party with your classmates and friends, and want to set up an impressive light display to entertain them. From your study of fluids, you have come up with the idea based on the water flowing from the tank in the figure. You set up the tank as shown in the figure, filled to a depth h 1.15 m, and sitting on a stand of height { 0.300 m. You punch a hole in the tank at a height of Y1 = 0.102 m above the stand. (Ignore the thickness of the tank in your calculation.) You want to punch a second hole higher on the tank so that the streams of water from the two holes arrive at the same position on the table, in a catch basin at a distance d from the right edge of the stand. A pump will continuously carry water from the catch basin back up to the top of the tank to keep the water level fixed.
