Задача id16484

A diving bell of height h = 3.0 m with a constant cross-section is lowered into the sea to a depth of H = 80 m. To what height h0 will the water rise in the bell when it reaches depth H, if the water temperature at the surface is t1 = 20°C, and at depth H temperature t2 = 7°C? To what pressure p0 must the air pumped into the bell be brought to completely remove water from it? The density of sea water is p = 1.03·103 kg/m3.
