Two communicating vessels with identical cross sections are connected by a tube, the cross-section of which s is 10 times smaller than the cross-section of the vessels S (Fig.). Water is poured into one of the communicating vessels, and oil into the other, the densities of which are p1 = 1 103 kg/m3 and p2 = 0.85 103 kg/m3. By what distance dl will the interface between liquids in the tube shift if a layer of the same oil with a thickness of dH = 2.0 cm is poured onto the surface of the water?
