![A side-view diagram of a vertical cylindrical tank. The top surface of the fluid is indicated by a horizontal line with a small inverted triangle. A small oval-shaped submersible is positioned deep in the fluid. A vertical dimension line with arrows extends from the surface to the center of the submersible, labeled h = 50 m. The fluid in the tank is labeled rho = 1200 kg per cubic meter.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1775617928-bsW2VL.jpg)
