Introduction
Welcome to our page about buoyancy force! Buoyancy force is the upward force that a fluid exerts on a submerged object, countering the object's weight. Here you will find an overview of the concept of buoyancy and a calculator to help you determine the buoyancy force on an object in a fluid.

Explanation
As we know from calculating the static pressure in a fluid, pressure increases with depth. If we considers a column of fluid, the pressure at the bottom is greater than the pressure at the top.
In this same way, the pressure at the bottom of a submerged object is greater than the pressure at the top of the object. This results in a net upward force due to the pressure difference, and is proportional to this difference in pressure. As explained by Archimedes principle, this force is equal to the weight of the fluid displaced by the object.

We calculate the buoyancy force using the following equation:
