In the manometer as shown, 2 immiscible fluids - mercury (ρ=13600 kg/m3) and water (ρ=1000 kg/m3) are used as manometric fluids. The water end is exposed to the atmosphere (100 kPa) and the mercury end is exposed to a gas. At this position, the interface between the fluids is at the bottom most point of the manometer. The value of h is found to be 9.45 m. The height of the mercury column is given to be 75 cm. Find the gauge pressure of the gas. (g=9.8 m/s2)
