As shown in the figure, a steady isovolume inviscid fluid of density p (blue) flows from left to right within a horizontal duct. The perfect fluid assumption can be used in this case. The diameters of the duct at the sections '1' and '2' are D1 and D2, respectively. Two vertical tubes are connected to the duct at these two sections. The top of the whole device is open and directly in contact with the atmosphere. Inside the left vertical tube, there is a segment of a light fluid (red) of density po, between the points 'A' and 'C'. In addition, the point 'B' indicates the position of the free-surface in the right vertical tube. We define that H = ZA ZB and h = Zc - ZA with ZA, ZB and Zc being the vertical coordinates of the points 'A', 'B' and 'C', respectively.
