The figure shows that the water in the tank is pressurised by the air an pressure is measured using a multi-fluid manometer. Given that the atmospheric pressure is 105.6 kPa and the heights of liquid columns are h1 = 0.1 m, h2 = 0.2 m and h3 = 0.35 m, and fluids are water, oil and mercury respectively, what is the pressure inside the vessel? Densities of water, oil and mercury respectively, are 1000 kg/m3, 850 kg/m3 and 13,600 kg/m Oll AIR WATER Mercury
