A cylinder container and a rectangular prism container are both filled with same but unknown fluid. The fluid in the cylinder is 8 meters high while the fluid in the rectangular prism is 7 meters high. The radius of the cylinder container is 1.5 meters while the side of the rectangular prism is 3 meters by 5 meters. Which container experiences less fluid pressure at the bottom given that both containers are resting on the floor?

Question

A cylinder container and a rectangular prism container are both filled with same but unknown fluid. The fluid in the cylinder is 8 meters high while the fluid in the rectangular prism is 7 meters high. The radius of the cylinder container is 1.5 meters while the side of the rectangular prism is 3 meters by 5 meters. Which container experiences less fluid pressure at the bottom given that both containers are resting on the floor?

The cylinder container
They have the same fluid pressure at the bottom since they are resting on the same level.
There is not enough information to determine the answer. The density of the fluid is unknown.
They have the same fluid pressure at the bottom since they are not covered and the atmosphere balances the pressure.

Answer 1

Both containers experience the same fluid pressure at the bottom since they are resting on the same level. The fluid pressure at a certain depth is determined by the height and density of the fluid, as well as the gravitational acceleration. In this case, the height of the fluid and the weight of the fluid (which is determined by the density) are the same for both containers, so they experience the same fluid pressure at the bottom. Additionally, both containers are open to the atmosphere, so the pressure from the atmosphere balances the fluid pressure. Therefore, the answer is: They have the same fluid pressure at the bottom since they are resting on the same level.
