Question

The water in a tank is pressurized by air, and the pressure is measured by a
multi-fluid manometer as shown in Figure 3. The tank is located on a mountain
at an altitude of 1400 m where the atmospheric pressure is 85.6 kPa. Take the
densities of water, oil, and mercury to be 1000 kg/m3
, 850 kg/m3
, and 13,600
kg/m3
, respectively. If h1= 200 mm, h2 = 100 mm, and h3 = 350 mm, calculate;
Pressure at point X
