A U-tube manometer has mercury, density 13 600 kg/m³, as the manometric fuid. One of the limbs is open to the atmosphere. If the level of mercury in the limb open to the atmosphere is 100 mm higher than that in the other limb, what is (a) the gauge pressure, (b) the absolute pressure in the closed limb. The atmospheric pressure is 101 kPa.
