Задача id10639

The vessel contains two immiscible liquids with densities p1 and p2 (Fig.). The pressure above the free surface is measured by a pressure gauge. Determine the excess pressure at the base of the vessel if рм = 102 N/m2; p1 = 890 kg/m3; p2 = 1280 kg/m3; h1 = 2.1 m; h2 = 2.9 m; g = 10 m/s2.
