A concrete slab in water has a buoyancy force of 5000 N. What is the slab volume?
| September 7, 2021 | education
Initial data: Fa (buoyancy force that acts on the concrete slab) = 5000 N.
Reference values: ρ (density of water in which the concrete slab is immersed) = 1000 kg / m3; g (acceleration due to gravity) ≈ 10 m / s2.
The volume of a concrete slab can be expressed from the formula for calculating the Archimedes force: Fa = ρ * g * V, whence V = Fa / (ρ * g).
Calculation: V = 5000 / (1000 * 10) = 0.5 m3.
Answer: The volume of the concrete slab is 0.5 m3.
