A simple U tube manometer is used to measure the pressure of oil flowing in a pipeline. Its left limb is open to the atmosphere and the right limb is connected to the pipe. The center of the pipe s 59 mm below the level of mercury in the left limb. If the difference of mercury level in the two limbs is 137 mm, determine the gauge pressure of the oil in the pipe in Pascal. The specific gravity of the oil & mercury is 0.72 and 13.6 respectively.
