The water in a tank is pressurized by air, and the pressure is measured by a multifluid manometer as shown in the figure.Determine the gage pressure of air in the

tank if h = 0.3 m, h2 0.3 m, and h3= 0.55 m. Take the densities of water, oil, and mercury to be 1000 kg/m3, 850 kg/m3, and 13,600 Km, respectively. (Round the final answer to two decimal places.) The gage pressure of air in the tank is КРа.
