A rectangular freshwater fish tank with base $2 \times 4 \mathrm{ft}$ and height $2 \mathrm{ft}$ (interior dimensions) is filled to within 2 in. of the top. (a) Find the fluid force against each end of the tank. (b) Suppose the tank is sealed and stood on end (without spilling) so that one of the square ends is the base. What does that do to the fluid forces on the rectangular sides?

Step 1
Since the tank is filled to within 2 inches of the top, and the height of the tank is 2 feet (24 inches), the depth of the water is 24 - 2 = 22 inches, or $\frac{22}{12} = \frac{11}{6}$ feet. (a) Show more…

An open rectangular tank is $2 \mathrm{m}$ wide and $4 \mathrm{m}$ long. The tank contains water to a depth of $2 \mathrm{m}$ and oil $(S G=0.8)$ on top of the water to a depth of $1 \mathrm{m}$. Determine the magnitude and location of the resultant fluid force acting on one end of the tank.
