Floating
Buoyancy refers to the forces that flow to the floating point in the fluid upward. Note that this effect only shows the effect of the fluid on the body, and other forces such as weight and support force can exist.

The floating force is related to the difference in the pressure applied to the body from the top and bottom. So :

Floating

We know that the pressure at the bottom is greater than the top of the cube. Because the object with a height h and a fluid density ρF brings more force down. The force applied to the bottom of the cube is obtained as follows:

ρF: fluid density

V: Moved fluid volume

A: The area of the object

mF: displaced water mass

h: The height of the object in the fluid

wF: The weight of the fluid displaced by the object

Archimedes principle
To any object dipped in the fluid, a force equal to the weight of the fluid displaced upwards is introduced.

This law is true for any object of any size and density.

If the object is completely immersed, VF = Vo means the whole volume is immersed.

Whether the object is drowned depends on the density of the body and fluid relative to each other if ρo <ρF remains floating. If ρo> ρF the object will be drowned.

B: Float force

wo: body weight in fluid

ρo: the density of the object

ρF: fluid density

Vo: Immersed object volume

VF: Moved fluid volume

If the whole body floats, that is to say, it does not drown, it does not come out, in this case the forces entering the body are zero.

In this case, we can conclude:

Why, when the diver goes to the bottom of the dive, water brings a force upwards to him?

The floating force is due to the hydrostatic pressure difference. Water in all directions exerts pressure on the body of the diver, but this pressure is higher on the side of the diver, because the lower side is in greater depth. As the water presses from the top to bottom and from bottom to top, the force is upward from the downward force. The difference between these two forces is the same as the floating force. Let's consider the space on which there is a pipe on one side and in it we pump up the water pipe. Then put a rectangular box inside the water. This box moves some water to its volume and drains the water from the pipe ... Continue

A float that enters the fluid in full or in part introduces a force equal to the mass of the fluid displaced over the floating body. In another language: Anyone who wants to enter a ball is sure to encounter a strong restorer force. This force, whose direction is upward, is known as the "floating force". All fluids are brought to any body in them ... Continue

Buoyancy is the tendency of an object to float. In this study, the students will learn the mechanisms and mathematics of floating. Or, in other words, what keeps floating objects up and how far the objects protrude above the water
