Two closed vessels contain water. Free surfaces are located in relation to the comparison plane O - O at heights h1 = 1 m and h2 = 1.8 m (Fig.). Pressure gauge reading p1 = 1.2•105 N/m2, difference in mercury levels in the differential pressure gauge ?h = 200 mm. Determine the pressure on the free surface of the second tank p2.
