A U-tube mercury (Hg) manometer as shown below is employed to measure the pressure of an oil-filled vessel. The densities of Hg and oil are 13600 kg/m3 and 800 kg/m3, respectively. The gravitational acceleration may be taken as 10 m/s2. The gauge pressure (in Pa) at point A when h1 = 0.5 m and h2 = 0.9 m, is approximately
