What is the Archimedean force acting from the atmospheric air on a person with a volume of 70 dm³? Air density 1.3kg / m³.
These tasks: V (the volume of the considered person) = 70 dm3 (in the SI system V = 0.07 m3).
Constants: g (acceleration due to gravity) ≈ 10 m / s2; according to the condition ρw (air density) = 1.3 kg / m3.
To determine the required Archimedean force acting on the person under consideration from the air side, we apply the formula: Fa = ρw * g * V.
Calculation: Fa = 1.3 * 10 * 0.07 = 0.91 N.
Answer: The effective Archimedean force is 0.91 N.
