EXERCICE 3.
On considère un tube en U contenant trois liquides :
- de l’eau ayant une masse volumique ρ1 = 1000 kg/m3,
- du mercure ayant une masse volumique ρ2 = 13600 kg/m3,
- de l’essence ayant une masse volumique ρ3 = 700 kg/m3.
On donne : Z0 – Z1 = 0,2 m Z3 – Z2 = 0,1 m Z1 + Z2 = 1,0 m
On demande de calculer Z0, Z1, Z2 et Z3.
Consider a U-shaped tube containing three liquids: - water
with a density ρ1 = 1000 kg/m3, - mercury with a density ρ2 =
13600 kg/m3, - gasoline with a density ρ3 = 700 kg/m3 Consider a U-shaped tube containing
three liquids: - water with a density ρ1 = 1000 kg/m3, - mercury with a density ρ2 = 13600
kg/m3, - gasoline with a density ρ3 = 700 kg/m3
We are given
Z0 – Z1 = 0.2 m, Z3 – Z2 = 0.1 m, Z1 + Z2 = 1.0 m
We are asked to calculate Z0, Z1, Z2 and Z3.
