Task 30 Closed tank A, filled with fresh water, is equipped with a vacuum gauge and a piezometer. Determine the absolute pressure P0 above the free surface in the tank and the height of immersion of water in the piezometer h, if the depth of water in the tank H = (2.2 + 0.1i), and the difference in mercury levels in the vacuum meter h1 = 80mm.Hg.

H = (2.2 +0.1i) = (2,2+0,1*5) = 2.7 m
