The total pressure in a gas pipeline is to be maintained at three times atmospheric pressure. Figure 3 shows the cross-sectional area of the pipeline that is connected to a manometer filled with mercury. An inspector measures a difference of 1.25 m between the two columns of mercury. Is the gas pressure being maintained at the desired value? The density of mercury is 13600 kg/m3.
