Find the fluid force exerted on the bottom of the container.

3. Fluid Force – Constant Force
Find the fluid force on a rectangular metal sheet measuring 2 feet by 3 feet that is submerged in 5 feet of water.

4. Fluid Force – Variable Force
Find the fluid force on the vertical side of a rectangular tank with dimensions 5 ft. by 4 ft. The tank is completely full of water.

5. Fluid Force – Variable Force
A vertical gate in a dam has the shape of an isosceles trapezoid 8 meters across the top and 6 meters across the bottom, with a height of 5 meters, as shown below. What is the fluid force on the gate when the top of the gate is 4 meters below the surface of the water?
4 m
8 m
5 m
6 m

6. Fluid Force – Variable Force
A circular observation window on a marine science ship has a radius of 1 foot, and the center of the window is 8 feet below water level. What is the fluid force on the window? (Density of water sea water is 64.0 lb/ft3 )
