Freshwater and seawater flowing in parallel horizontal pipelines are connected to each other by a double U-tube manometer, as shown in Fig. P2- 62. Determine the pressure difference between the two pipelines. Take the density of seawater at that location to be p = 1035 kg/m3 . Can the air column be ignored in the analysis?
