Example 7.4: A U-tube manometer is used to measure pressure drop across an orifice meter. The manometric fluid is mercury (sp. gr. 13.6) and fluid flowing through the pipeline and filling manometric leads is brine (sp. gr. 1.26). When the pressure at taps are equal, the level of mercury in the manometer is one meter below the taps. In operating conditions, the pressure at the upstream tap is 115.324 kN/m? absolute and that at the downstream tap is 33.864 kN/m³ below the atmospheric pressure. What is the reading of manometer in centimeters ?
