Let's calculate the uplift force

Calculate the buoyant force on the body using the buoyancy formula. Answer the question.

What are we dealing with here

At the beginning of the lesson, we got acquainted with the formula for calculating the uplift force.

F_{¨ u} = ρ V g

Now let's find the necessary parameters to use the formula and calculate the uplift force acting on the body.

Finding the volume of a body

The volume of the body can be calculated by measuring the diameter and height of the bottom of the cylinder. Or it can be determined using the scale of the measuring cylinder. Carry out the measurements, record the results in the table.

The reading of the measuring cylinder before submerging the body in water ( $[m l]$ )
The reading of the measuring cylinder after immersing the body in water ( $[m l]$ )
Volume of the test object ( $[m l]$ )
Volume of the test object ( $[m^{3}]$ )

Let's calculate the lift force

Body volume( $[m^{3}]$ )
Density of water ( $k g / m^{3}$ )
Gravity acceleration ( $m / s^{2}$ )
Buoyant force acting on a body in water ( $[N]$ )
