Key Concepts

Archimedes' Principle

This principle states that a body submerged in a fluid experiences an upward buoyant force that is equal to the weight of the fluid it displaces. It is a fundamental concept in fluid mechanics and underpins the understanding of why and how objects float or sink in a fluid, regardless of the overall shape of the object.

Density Ratio and Equilibrium

When an object is floating, its weight is supported by the buoyant force, meaning the weight of the displaced fluid equals the object's weight. Consequently, the fraction of the object's volume submerged is directly proportional to the ratio of the object's density to the density of the fluid. This relationship provides a straightforward method for calculating the immersed volume fraction without needing to consider the object's shape.
