A submersible is a small, specialized ship or vessel that operates under the water's surface.

Consider a research expedition using a deep-sea submersible to investigate marine life. The buoyancy control system uses ballast tanks to adjust buoyancy, allowing it to dive to a depth of 1000 meters safely.

Exploring the buoyancy control involves understanding buoyant forces. Archimedes' Principle is fundamental, stating that the buoyant force on a submerged object is equal to the weight of the water it displaces. Mathematically, it can be expressed as:\[ F_{b} = \rho \cdot V \cdot g \]Where:\( F_{b} \) = buoyant force,\( \rho \) = density of the fluid,\( V \) = volume of fluid displaced,\( g \) = acceleration due to gravity.Understanding these calculations aids in designing efficient buoyancy systems, optimizing the submersible’s functionality and safety.
